Who knew they were such good friends?

Kris Jenner is currently on a girls' vacation in Mexico with pal Melanie Griffith and her daughter Dakota Johnson, and the momager doesn't look like distraught woman going through a breakup, even though it's been reported that she called it quits with her boy toy Corey Gamble.

"Kris was using him for someone to hold and she was using him for sex. He gave her what she needed for that moment in time. When Kris started to hear the reports in the media from Corey’s ex-girlfriends, she really started to lose interest and see him as a liability," a source dished to Radar.

"Kris is an opportunist and she has traded up men her whole entire life. She is always looking for something bigger and better," the source added.

It certainly didn't look like the couple was dunzo when we caught Corey fueling up his much older lady love's Bentley in L.A. just yesterday!

Steve-O may be a 40-year-old man, but he's still acting like a wild teenager, smashing cars and being a wild child.

On Wednesday night, the former Jackass star was got a little crazy as he got on top of the hood of his beat-up car and smashed it for onlookers.

The former Dancing with the Stars contestant was coming from Demi Lovato's charity event, the first annual Lovato Treatment Scholarship Program fundraiser, which was held at the Troubadour in West Hollywood.

It seems like the charity function revved him up because afterwards he couldn't control himself. The funnyman even took video of the incident on his cell phone.

After the charity even, Steve-O posed with fans and talked about he's still a rebel, despite no longer being up to his wicked ways.

"I am seven years sober, but I am still a maniac," said Steve-O.

Ya can't keep a wild man down!

Jennifer Lopez arrived at the set of American Idol on Wednesday afternoon, and while she's always been a babe, she wasn't exactly glammed up when she walked into the studio -- Jenny from the block was wearing sweatpants!

But in typical J. Lo fashion, she looked amazing, and she draped a fur (hopefully faux) over her shoulders and rocked a pair of high-heeled sneakers. And can we talk about how perky her infamous booty is? We always have a hard time believing that she's 45 years old!

In addition to her Idol duties, J. Lo is currently developing a new series for NBC called California, and according to reports, she's in talks to appear on an episode of Empire next season. Whew! So what else has she been up to? Oh you know, just having casual lip-syncing contests with Pitch Perfect star Anna Kendrick on the side!

In a new promo for Lip Sync Battle, which is a competition show based off the skit created by Jimmy Fallon, the ladies went at it to J. Lo's hit "Booty." As much as we love the two of them taking the stage, we have to say, Stephen Merchant is totally amazing at the end:

Breaking up is hard to do... even the third time around!

Katy Perry and John Mayer have called it quits again after briefly reconciling after the pop star finished her tour earlier this year, Radar reports.

"Katy and John reconnected once she had a break in her Prismatic World Tour. So, for those few months they had a great time, pretending that it would last — and of course it didn’t. The reason they have split in the past is because Katy gets busy. John can’t handle the lack of attention, and she can’t handle the trust issues she has when she’s so far away," the source dished about the couple's issues.

The lovebirds have been on and off since the songstress' marriage to Russell Brand ended in 2012. The pair last parted ways last February, but then were spotted in January of this year spending time together. The "Gravity" crooner even accompanied his lady love to the Super Bowl this year.

If they're really dunzo, we hope those rumors that the brunette beauty has a bun in the oven aren't true!

She's got a spring in her step, and now we know why!

Katie Holmes went to visit a girlfriend in L.A. yesterday, and the actress didn't look stressed at all that news had just broken she was dating Jamie Foxx. In fact, she looked more put together and cheerful than we've seen her in a long time. We couldn't be happier for the Dawson's Creek star that she has romance in her life after all these years being single since her split from Tom Cruise.

The single mom and the Ray actor have been enjoying secret hookups for over a year, People first reported. Rumors popped up that the pair were seeing each other in August 2013, so the couple was able to keep it hush hush for longer than most people in Hollywood!

"This is not some intense romance. Jamie and Katie are friends and have been for a long time. They are two adults who are attractive and single, and so apparently conclusions will be drawn," a source dished to the mag. "But contrary to those conclusions, they're not about to run off and make some serious commitment," the source added.

Although, a pic of the duo holding hands in a recording studio surfaced yesterday, and it certainly looks like more than a fling! We have a feeling they are trying to downplay their connection to maintain a level of privacy. Be loud and proud about your love, guys!

Not only does Rumer Willis dance like a pro, but she looked gorgeous when we snapped her arriving at Dancing With The Stars practice on Wednesday. She's always had a fab figure, but with all that fancy footwork, her body is better than ever!

Earlier this week Rumer took home the highest score of the night on the hit ABC show, and she was supported by her sisters Scout and Tallulah, along with mom Demi Moore and dad Bruce Willis. Bruce brought wife Emma Heming, and while everyone was in good spirits, Demi and Bruce didn't speak. Hey, as long as they both came out to support their oldest daughter, that's all the counts, right?

Madonna may have butted heads with Elton John in the past, but she's totally on his side now in the fight against designers Domenico Dolce and Stefano Gabbana for their shocking comments about IVF.

If you're not familiar with the story, it all started when the D&G boys chatted with Italy's Panorama magazine and slammed gay adoptions, remarking that children created via IVF were "synthetic." Elton, who has two children born via surrogate with husband David Furnish, wrote on Sunday on his Instagram account, "How dare you refer to my beautiful children as 'synthetic.' And shame on you for wagging your judgmental little fingers at IVF - a miracle that has allowed legions of loving people, both straight and gay, to fulfill their dream of having children."

Elton then asked his famous friends to boycott the fashion label, and though Ricky Martin and Courtney Love came through, on Monday the "Tiny Dancer" singer was photographed carrying a D&G shopping bag. Oops! A rep for Elton told E! News, "Yes he was carrying the bag but he hadn't been shopping. And it should not detract from their original message or the boycott." Hmm, we're not buying it...

After watching Elton and D&G go back and forth, Madonna chimed in on Wednesday night by sharing a photo on Instagram of her ad for D&G's Fall/Winter 2010 collection in which she's lying on a bed with a baby in her arms. The queen of pop wrote:

"All babies contain a soul however they come to this earth and their families. There is nothing synthetic about a soul!! So how can we dismiss IVF and surrogacy? Every soul comes to us to teach us a lesson. God has his hand in everything even technology! We are arrogant to think Man does anything on his own. As above so below! Think before you speak #livingforlove."

And there you have it!

Demi Lovato held her first annual Lovato Treatment Scholarship Program fundraiser at the Troubadour in West Hollywood on Wednesday night, and not only was she accompanied by on-again (and much older) beau Wilmer Valderrama, but her ex Joe Jonas DJed the event! Demi and Wilmer have been on and off for years, but after Demi claimed Joe broke her heart back in 2010, we weren't sure if they were on good terms. Now we know!

And speaking of Wilmer, just a few days ago Demi expressed her love for him in an Instagram post, thanking him for being by her side during the tough times. "I wish I could put into words how grateful I am for this man right here,” she captioned a black and white photo of them kissing. “But my love has grown to a level that words could never possibly express how much this man completes me. He’s loved me the way I never thought I deserved to be loved and with this day making my 3rd year sober… After sharing my ups, putting up with my downs and supporting my recovery… he still never takes credit and I want the world to know how incredible his soul is. I really wouldn’t be alive today without him. I love you Wilmer."

Anyway, who else attended the event? In addition to several speakers, there were performances by Bea Miller, Christina Perri and Sirah, and Khloe Kardashian and Lance Bass showed their support as well. Demi thanked her famous friends for attending and added, "Each dollar we raise supports the Lovatic Scholarship & helps those struggling with mental health + addiction issues.” The scholarship fund "covers expenses for individuals struggling with mental health and/or addiction issues."

Good for her!
