Ashlee Simpson was spotted meeting up with a friend for lunch today in Studio City, wearing her favorite Anine Bing jeans, and while the singer/actress has always been on the slimmer side, it looks like she's lost even more weight over the last few weeks.

We're not sure what's eating away at her, but rumor has it she's barely on speaking terms with her big sister Jessica! According to a source for OK! Magazine, Jess turned to Ashlee for support this summer when she was trying to lose her baby weight, but when Ashlee "showed very little sympathy for her, Jess lost it." The source added that Ashlee believes Jessica “only has herself to blame” for her weight troubles. Ouch!

“She was devastated and hit back, saying Ashlee is jealous of the attention she gets. It turned into a massive fight," the insider added. “Ashlee used to feel like they were friends. They would party together, but ever since Jess decided to have a baby, she’s way more straight-laced. It’s alienated Ashlee.” Hmm, think any of this is true?

Who knew The Situation loves kitties THAT much? Um, yeah.

The Jersey Shore hunk is striking a shirtless pose in a new PETA campaign ad ... raising awareness for spaying and neutering cats.

Mike Sorrentino posted the above photo and the following, "It was a pleasure working with @peta on this campaign. A great cause with an important message! #support."

We all know Sitch loves to chase that tail!

Bombshell in the Big Apple alert!

Salma Hayek wore a beautiful green dress that hugged her curves in all the right places to a taping of the Wendy Williams Show in NYC today, and the 46-year-old actress doesn't look a day over 20!

The key to the brunette beauty's stunning looks is apparently a good state of mind! Not only is joy good for her looks, it's also good for comedy roles!

"Maybe before it was harder for me to make people laugh. Now it's the opposite. It's hard to cry. The truth is I'm very happy to be happy," she recently admitted to EFE. "When I was young, I was much more melodramatic. As an actress, there were times I even enjoyed pain, suffering a little. Well, I didn't enjoy it, but I had an inclination toward melodrama. I was good at making people cry. Now, when I have a character that suffers, where you have to [do some soul searching] I can do it no problem, but I prefer making comedies," she confessed.

When you are smoking hot, married to a billionaire, have a booming career and an adorable daughter, it's not hard to be a happy camper!

Hilary Duff is focused on shedding that baby weight with regular trips to the gym!

The former Disney darling, wearing black stretch workout pants, a grey tank and a camel-colored scarf, fed the meter while holding on to her essentials ... her Starbucks drink and iPhone 5.

When asked about her weight earlier this year, Duff told Us:

"Obviously, I'm not where I want to be eventually, but I'm working hard and I'm doing everything I can to lose the weight the right way. The second I start to get down like "What happened to my body?" I look at my beautiful baby and I've never been more appreciative for this body that I have."

Duff, who gave birth to son Luca in March, has been hitting the gym hard, and it shows!

There's no such thing as not being camera-ready in Kardashian world!

Kim and Khloe Kardashian arrived back at their Miami hotel today, presumably after a long day of filming their spinoff show, and for the first time in forever the girls didn't appear to want their picture taken. Shocker!

Kimmy K's ex-boyfriend Reggie Bush just announced he's expecting his first child with girlfriend Lilit Avagyan, and although rumors swirled that the reality star was "devastated" by the news, it sounds like marriage and a baby aren't far off for her, either!

The brunette bombshell's boyfriend Kanye West had the new track "White Dress" leaked online, and it doesn't take a detective to figure out who he's referring to in the rap song.

"You the type of girl who deserve a new last name"/"Your high heels clicking, you lip gloss glisten, your hips start switching..."/"Even when we kissing baby girl feel different, friends still diss me like no he didn't"/" Yeezy raps.

The most shocking lyrics of all? The Grammy winner's admission he wants Kim to be his bride!

"I see you in the club in a tight dress, but I picture you in a white dress," he adds.

A proposal before the holiday season seems like a given at this point!

Ke$ha covers the November issue of Vibe magazine, and we're used to the 25-year-old singer showing some skin in skimpy outfits, but we're not used to her looking like such a pin-up girl!

While she looks stunning in these pics, be warned ... she still has a potty mouth and says whatever is on her mind. “I came from a single-parent home, my mom had a nose ring and tattoos, and I’d make my own clothes,” she says of her teen years. “People just thought I was a f*cking freak.”

K Money adds that she still has to deal with the bullying from critics and haters, but she tries to brush it off. “I’ve really just been doing a lot of thinking about life,” she says. “The first record, people tore me a new a**hole, and were f*cking steady on my balls, and tried to make me feel like I was such a piece of sh*t. I did some soul-searching, and realized nothing I’m doing is negative, it’s actually super positive. You can change peoples’ mood in a three-and-a-half minute song. So why not spread positive energy and be funny? Let [the haters] be miserable. Anyone who wants to have a good time, let’s f*cking do this.”

“If I tried to pretend to be something I wasn’t, people would have smelled bullsh*t a long time ago,” she continues. “I would've gotten eaten alive if I tried to be a heel-wearing little princess. It’s just not who I am. I’ve had people try to make me act right, but it’s just not gonna happen. I just can’t not say inappropriate things.”

And that's why we love her!

What a difference a year has made for Tamara Ecclestone!

The eldest daughter of Formula 1 billionaire Bernie Ecclestone and Croatian model Slavica hit the runway for designer Atil Kutoglu for Istanbul Fashion Week looking a bit more plus-size as compared to her former self.

Perhaps Tamara's wealthy sister, Petra, will give the runway a try. Oh, the life of an heiress!
