Another one bites the dust?

Nick Cannon just confirmed to The Insider that he and wife Mariah Carey's marriage is on thin ice and they have been under two different roofs in recent months. "There is trouble in paradise…we have been living in separate houses for a few months," he told guest co-host Chris Spencer.

So what went wrong with the former love birds?

Apparently the Grammy winner went ballistic when her hubby made an appearance on Big Boy's radio show in May and revealed he slept with Kim Kardashian back in the day, TMZ reports. Mimi didn't appreciate the father of her children publicly revealing those facts, and tore into him for weeks to the point that their relationship never recovered. It got worse when Cannon told Howard Stern how the singer made him wait for sex until after they got married.

Beyond that, the "Beautiful" songstress had a big issue with her spouse's work ethic, claiming that every gig he accepted took him away from her and his family when they really didn't need the money in the first place.

Can anyone stay together in Hollywood these days?!

In fact, Jared Leto was feeling so good when X17 photographers snapped his photo last night, he gave us his usual thumbs up!

On Wednesday evening the Oscar winner was spotted at the Bowery in New York City after appearing on The Tonight Show With Jimmy Fallon, and oddly enough, Lindsay Lohan arrived at the hotel just a little bit before him! Seeing as the two aren't exactly besties (I mean, he's not on her sex list and the two reportedly squabbled when they shot Chapter 27 several years ago), we doubt they were meeting up. Still, there's always the chance of an awkward encounter!

And speaking of awkward encounters, earlier in the day, an interview with Alexis Arquette hit the web in which the transgender starlet claims she slept with Leto -- BEFORE she made the transition from male to female! Arquette told Frontiers LA, "I had sex with Jared Leto back when I was presenting as a male. And, yes, it's not only massive -- it's like a Praetorian Guard's helmet." Hey, at least she was kind enough to mention how well-endowed he is ... but do we REALLY believe this? Especially when you consider that Jared could have his pick of pretty much anyone in Hollywood (or anywhere in the world, for that matter)...

Must be nice to have airport personnel whisk your $4,000 Louis Vuitton suitcase through the terminal while you 'gram it up on your iPhone and pretend to ignore the paparazzi!

Kendall Jenner arrived at LAX on Wednesday evening, and the 18-year-old reality star/model was glued to her cell as she walked outside. Kendall squeezed her hot bod into a pair of skintight leggings, and her sweatshirt had a bizarre and rabid-looking rabbit emblazoned on the front. Er, is that the bunny from Donnie Darko? Kids these days...

Kendall recently made headlines with the news that she's struck up a romance with 25-year-old Dallas Mavericks star Chandler Parsons, who just signed a three-year, $46 million contract with the NBA franchise. A source told the Daily Mail that mom Kris Jenner has already met Chandler, and she was "blown away by not only his good looks, but his promising B-ball future." But that could be a problem too. "Everyone knows that when you date a Kardashian you have to deal with Kris, who is totally enmeshed in the lives of her kids," the insider told the site. "No matter how hot Kendall is, it’s not worth it."

Still, that didn't seem to deter Chandler from going on a date with Kendall last month at STK, so maybe this will be different? And since there's rumors Kendall is looking to quit Keeping Up With The Kardashians so she can focus on her fashion career, it does seem like she's looking to get out of Kris' momager claws as much as she can...

Yikes! Lindsay Lohan's side profile certainly isn't her best shot...

On Wednesday evening the 28-year-old actress arrived at the Bowery hotel in New York City for dinner, and if she was trying to impress someone with her hot bod and impeccable taste in clothes, she definitely picked the wrong outfit. Anyone can appear to have a double chin when photographed from the wrong angle, but the fact that Lilo wore a top that exposed her floppy tatas and bloated belly was just not a good move.

And speaking of bad news, Lindsay's credit card was reportedly declined at 1Oak in Southampton on Saturday night, reports the New York Post. Apparently the starlet was trying pay the $2,500 bill for her table and bottles of vodka, and a source tells the paper, "Lindsay freaked out when her card was declined. Her friends and others in her group had to chip in to cover the bill."

Back at the clubs, eh? It doesn't seem to matter if she's in LA, the Big Apple or London, some things never change!

Zac Efron is now a single man, so why NOT cozy up to his smokin' hot co-star, Emily Ratajkowski?

On Wednesday the news broke that Zac and much older lady love Michelle Rodriguez had split, and that same afternoon we snapped the 26-year-old actor on the set of We Are Your Friends in Los Angeles, and after working up a sweat on a run, he got super close to Ms. Ratajkowski. The previous day we spotted him flexing his muscles and giving a male pal a back massage, so who knows what he'll be up to today!

The film is about a young DJ named Cole who ends up falling for the girlfriend of his mentor, and between the love triangle, Zac's ridiculously fit body and a soundtrack that's aimed to appeal to a younger demographic, it sounds like this movie could be pretty interesting. Or pretty bad. But still, pretty interesting, right?

Someone get this man some shades!

Justin Bieber was blinded by the sun as he headed to the recording studio today in Hollywood, and we're a little surprised he didn't sport some fashionable sunglasses to protect his precious peepers!

We would say he looks a little hungover, except apparently he's toning down his wild ways now that he's back with Selena Gomez. If you believe the reports, the "Come & Get It" singer has inspired The Biebs to clean up his act. “Justin is getting really healthy, he wants to look good for Selena so he’s working out a lot, they’re both on a health kick. They’re detoxing from all the partying and negativity right now. He’s been hiking every day, that’s his new favorite thing. And he’s getting up early because he’s not out partying all night, he’s just been at home chilling with Selena,” a source tells Hollywood Life.

So will Jelena last this time around?

"He is more in love with her than ever because he realized that he could have lost the best thing that ever happened to him for good. Of course these words were music to her ears. Selena said she would take him back on one condition–that they get ‘spiritual’ counseling together," the source added.

We bet he's recording love songs in the studio!

Rob Pattinson accepted Zac Efron's ALS Ice Bucket Challenge -- and then some!

On Wednesday Zac posted the video above on YouTube and tweeted, "#RobPattinson’s not on social media, so he asked me to post his @ALSAssociation #IceBucketChallenge! It’s hilarious!"

Rob began by thanking Zac, and he added, "I didn’t have a bucket, you’ll notice I have to improvise." Rob proceeds to have a friend dump ice on his head while another pal blasts him with a powerful garden hose. Rob's buddies then pelt him with ice and spray him in the face again, and someone even throws a red Solo cup at the Twilight hunk.

R Pattz nominated Guy Pearce and Mia Wasikowska, and even though he bent the rules a bit on this, we have to say, we really enjoyed it...

Pregnancy has only made her even prettier than she already was!

Zoe Saldana went for a hike with pals in Hollywood this morning, and the actress' baby bump seems to be getting bigger by the day. Although she has yet to confirm the reports she's having twins, it seems pretty obviously to us that she's got more than one bun in the oven!

The Avatar star didn't wear a stitch of makeup and still managed to look flawless, and considering how hot her husband Marco Perego also is, their offspring will undoubtedly hit the genetic jackpot!
