We're almost sick of seeing her everywhere we look, but when Jennifer Aniston appeared on The Tonight Show Starring Jimmy Fallon on Wednesday evening, she totally made us crack up.

Jen and Jimmy played a game of lip flip, and she did an amazing job keeping a straight face as she attempted to go along with the words coming out of his mouth. Then the two got to talking about the Super Bowl, at which point Jen (well, Jimmy) started talking about marijuana. We honestly can't even describe this -- you just have to watch it!

On a more serious note, Jen's Hollywood Reporter cover story hit the web yesterday, and not only does she talk about Justin Theroux, but she recounted some painful details from her childhood. Jen opened up about her rocky relationship with her mom Nancy Dow, who penned a tell-all book about the two back in 1999 when Jen was at the height of her Friends stardom.

"She was critical. She was very critical of me," she tells the publication. "Because she was a model, she was gorgeous, stunning. I wasn't. I never was. I honestly still don't think of myself in that sort of light, which is fine." Er, how uncomfortable!

Jennifer Lopez took a break from promoting The Boy Next Door and attended the AOL Build Speaker Series in New York City, and we wouldn't dare to pull off this poufy Christian Siriano skirt, but J. Lo rocked it with flying colors. And can you believe she's 45?

Apparently age is just a number for the actress, because she revealed in the new issue of People that she wouldn't mind having more children -- specifically twins! "I have two happy healthy kids, so okay, good, we're doing all right," she said. "I don't know if it's in the cards for me because of my age, but I would love to have another baby, to be blessed one more time. I'd love to have twins again. I was thinking about that last night when I was in bed with Emme. I was just loving the moment. I don't know if it's in the cards, but you never know." If anyone could do it, it would be J. Lo!

The superstar is currently single, but she's not worried about finding love. After splitting from Casper Smart last spring, J. Lo tells the mag:

"I had to make a commitment to myself to be alone: no flirting. No possibility of anything. No boys in any way, shape or form. I said, 'I'm shutting it down.'

I always found my comfort in another person. Instead of giving myself time to heal and be on my own, I was so afraid to be that I was always like, 'Okay somebody else just come in here and help me forget I'm in so much pain. I was terrified of being alone. Listen, at the end of the day, love is the best thing. But what I've discovered is that I can't get that from somebody else. It's the love inside me, for myself, that will help me through."

Well put, J. Lo!

So what about getting back into the dating pool? "I still believe in the fairy tale," she says. "The more I work on myself, the more I give myself the opportunity to share a really deep and meaningful relationship that can give me my fairy tale and last forever." She added, "I'm not rushing into anything in any way, shape or form. And I'm not looking."

Justin Bieber and Hailey Baldwin still won't admit that they're a couple (and a few months ago Biebs even claimed they were just friends!), but at this point we basically have to call them liars. Come on! You don't go on dinner dates and romantic vacations with your hot model model female friend if there's not some spark there...

On Wednesday afternoon the super blonde duo went to lunch at Urth Caffe in West Hollywood, and they were dropped off in a fancy Mercedes. The did the same thing the previous day, so they really don't seemed concerned about maintaining a low profile.

Despite grabbing dinner with ex-girlfriend Selena Gomez last, Bieber is reportedly planning on taking Hailey on yet another romantic vacation. This time the lovebirds will head to a five star resort in Cabo San Lucas over the Valentine's day weekend, and a source tells OK! Magazine, "He’s definitely settling down a little and wants a serious girlfriend in his life again. He and Selena were just too toxic, but Hailey knows how to calm him down in ways Selena couldn't." We'll believe that when we see it...

Hailey didn't seem to mind the attention, but Biebs shielded his face before hopping into the car. Maybe don't pick one of the most popular eateries in the Los Angeles area if you don't want to be photographed? I mean, they even filmed Entourage here:

Britney Spears may not be performing in Vegas this week, but that doesn't mean she's taking it easy!

On Wednesday the pop star went to the gym in Los Angeles, and she flashed X17 photographers her megawatt smile before her workout. Britney will be back at the Planet Hollywood Resort and Casino next Wednesday for the latest leg of her "Piece of Me" residency, which runs through early March. Then Brit will have a little over a month off before the next round of shows, so she'll have plenty of time to be with her boys -- and her steady beau Charlie Ebersol!

On New Year's Day Brit posted a photo of the lovebirds, and we have to say, we haven't seen her this happy in a long time. Not only is he WAY better looking than her scummy ex David Lucado, but seems like a way better match for her. Awww!

Just what every man wants to hear a woman say -- you're just like my gay best friend!

In a revealing interview with the Hollywood Reporter, America's "No. 1 snubbed" actress Jennifer Aniston got candid about her struggle with dyslexia, her critical mother -- and her main squeeze: Justin Theroux.

In the sit down, the sitcom actress-turned-movie star said that Theroux's wit is what first attracted her to the motorcycle-riding, leather-wearing actor. "It was his humor, mainly ... He's the easiest guy to hang around. He was so completely in his skin," said Jennifer.

The Cake actress also admitted something we aren't sure most straight would want a love interest to say publicly: "It was the first time I remember being so comfortable [with a romantic interest], like with all my gay friends."

The 45-year-old also spoke of her fractured relationship with her mother, model Nancy Dow, who wrote a tell-all book called "From Mother and Daughter to Friends: A Memoir," which chronicled the life of he famous daughter. The harbinger of "The Rachel" confessed that things haven't been peachy with her maternal parental unit for quite some time."She was critical. She was very critical of me," said the beauty, who is also the daughter of soap star John Aniston.

In addition, Jennifer also revealed to the mag that she was diagnosed with dyslexia in her early 20s -- and that finding out that she had the developmental reading disorder caused her to change some negative perceptions about herself. "I thought I wasn’t smart. I just couldn’t retain anything. Now I had this great discovery. I felt like all of my childhood trauma-dies, tragedies, dramas were explained."

The TV icon also said that she's been working on her anger issues:

"I always thought, if you’re angry you just don’t say anything. I would come out passive, things would come out passively. But it doesn’t have to be black or white. You don’t have to be a hysterical human being and have veins popping out of your neck and turn bright red and terrify people — or else keep quiet and put your head in the sand. I used to loathe confrontation. Loathe it. It was absolute. I understood anger, but I didn’t know that you should express it. Which has been something that I’ve really tried to work on."

See even Jennifer Aniston can teach us all how to be better people!

He likes big butts and he can not lie ...

Kim Kardashian superfan Jordan James Parke, who has spent over $150K to look the way he does, had a sit-down with British talk show This Morning. During the interview, the over-the-top gent talked about the plethora of procedures he's endured to look like his idol, Kimmy K -- and that next he wants an ass that will break the Internet. Don't we all, darling ...

On the show, the heavily made-up 23-year-old explained: "I've had lip filler, obviously, I've had botox, I've had cheek filler, I've had chin filler, I have my eyebrows tattooed on, micro-dermabrasion, I get regular vampire treatments." Umm we just looked up "vampire treatments" and it's not good.

But even all that hasn't satisfied the beast -- Jordan curves like Kim's. "I love her bum, her bum's amazing. When she did the cover when the bum was out, I think she looked amazing, she's an inspiration," said Jordan.

Oh yes -- such an inspiration ...

Jordan, who says many of his procedures have been paid for by boyfriends, doesn't want to get implants, saying, "I'd like to go as big as her. I'm not going to get implants, I won't go down the route of implants."

The brow-tastic personality said, "I want to get liposuction on my stomach and back. I lost 70lb last year, I'm so lazy, I never exercise so I want to get lipo on my stomach and back and they put the fat back into your bum so you get two procedures in one and you get a big bum."

Thanks Jordan James Parke for teaching us all a valuable lesson: if you can't work out to get the body you want -- just buy it!

We have to agree!

Kris Jenner didn't know what they were talking about when photographers asked how she felt about Russell Brand coming to her ex Bruce's defense amid transitioning rumors at LAX yesterday, but once they told her the British comedian was taking a stand against the former Olympian's bullies, she was full of praise!

"Aw, that was nice - super sweet," she exclaimed as she made her way through the terminal.

In case you missed it, Katy Perry's ex urged the media and fans alike to leave the 65-year-old alone on his Youtube show. "This is bullying. Stop. Stop. Bruce Jenner is a human being. If you want to learn more about transgender issues, look at GLAAD.org. Transphobia seems to be the most recent and encouraged form of prejudice, now that racism and homophobia are not tolerated. It's such a celebration of the worst aspects of human values. What this does is it sanctions people being judgmental and cruel toward transgender folks," he explained.

The momager must love that at least people are talking about her famous family!

We figured Leonardo DiCaprio's messy beard was for a film role, and now we know a little bit more about it!

The first stills of Leo in Alejandro Gonzalez Inarritu's The Revenant appeared on Entertainment Weekly today, and he's been nominated (and shut out!) five times for a Best Actor Oscar, so could this be his ticket to a golden statuette?

In case you didn't know, The Revenant is a 1800s biopic about Hugh Glass, an American fur trapper who trekked 200 miles across Missouri after being mauled by a grizzly bear. Glass was on an expedition with several partners, but they left him for dead after the attack. We're not sure how things went down once Glass got back to camp, and frankly, we don't want to know -- we'd like to save that for the movie! Tom Hardy stars as one of Glass' pals, and the film will hit theaters next Christmas.

"He’s a brave, incredible actor. I’m so surprised about how good he is," Inarritu says of DiCaprio. "I think there’s a profound understanding of humanity that I can see through his eyes." We can't wait to get a peek at the first trailer for this!
