Uh oh ... is there really trouble in paradise?

On Friday afternoon Kourtney Kardashian, who is currently pregnant with her third child with baby daddy Scott Disick, landed at Los Angeles International Airport with daughter Penelope and son Mason -- but Scott was nowhere in sight. While Mason seemed entertained after the 5-hour flight, Kourt and especially little miss P looked a little bit grouchy. What's up with that?

Kourt has reportedly had it with Scott's partying and childish antics, and their relationship drama is on the cover of the latest issue of Us Weekly. Apparently the preggers reality star kicked Lord Disick out of their rented Hamptons mansion on June 9 -- right in the middle of shooting their spin-off show!

"Kourtney was yelling at Scott after she found an inappropriate picture of him with another girl," a source tells the mag. The mother of his children lost her cool in the driveway while cameras were rolling, and Scotty was forced to check into a nearby hotel for the night. Yikes!

"You need to be a more responsible father and get better. There is another baby on the way! You need to straighten up or get out!" she reportedly screamed during the argument. When we polled our X17 readers on Wednesday, we asked if you thought the fight was for real or for ratings, and though 75% of you think it's fake, the rest of you weren't so sure...

What a precious princess!

Kelly Clarkson just released the first photo of her newborn daughter River Rose Blackstock, and we can't believe how much the little one already looks like her famous mama!

"Here is our beautiful baby girl River Rose; 6lbs 6oz, 18 inches, and the greatest thing on the planet," she captioned the photo of her firstborn asleep in a red carriage.

The "Stronger" singer and her husband Brandon welcomed their baby girl on June 12th. This is the first child for the American Idol alum and her talent manager beau. Blackstock is also father to daughter Savannah, 11, and son Seth, 7, from a previous marriage.

Let's hope River didn't inherit a set of pipes from Kelly, or else these two are in for some sleepless nights!

OMG! He's sooooo cute!

Gwen Stefani went to her acupuncture appointment on Friday, and after getting poked, the No Doubt singer held on tight to her four-month-old son Apollo. While Gwen wore heels and a healthy application of dark lipstick, she kept it casual with rolled jeans and a grey tank. Sigh. Does she EVER look bad? And when you consider that she's 44 and the mother of three children, it makes us wonder if she's even human!

Zac Efron is taking his off for a good cause (no, unfortunately not because he is hopping into one of our beds) -- he's doing it for charity! The High School Musical alum showed off his toned chest while making skateboards for Lekker Skateboards. The company just released a video, that was soon taken down for copyright reasons but not before we got to see some hot shots of those killer abs!

Last week the 26-year-old tweeted about the experience, "My friend taught me how to make skateboards. Stay tuned to find out how you can win one & help an incredible charity."

In the vid, the Neighbors actor works with various machinery used to make the company’s unique brand of skateboards ... bla bla bla ... we don't care -- we only care that super sexy Zac Efron has no shirt on!

From one reality show to another!

Rob Kardashian made a rare appearance out in public to meet up with momager Kris Jenner in L.A. to discuss the possibility of appearing on the weight loss competition show The Biggest Loser!

The 27-year-old's weight has ballooned over the past year, and he's even been in hiding and skipped sister Kim's wedding because of his insecurities over his appearance, so his mom thinks this is the perfect opportunity for her son to get back into shape.

Apprently the Kardashian matriarch has been taking meetings with E! executives to convince them to throw around their weight - no pun intended! - and get him cast on the NBC program.

"With The Biggest Loser being on NBC, they share a lot of the same people who make decisions on E!, so Kris has been in meetings to see if it would work to have Rob on Season 16 this fall," a source dished to Hollywood Life.

The only one who still needs some convincing is Rob!

"Everyone is on board for this to happen except Rob, he still needs convincing. But most people involved in the talks think Kris will get her way and have him join the show," the source added.

We think this would be life changing for him!

Umm Gross. We get that couples like to spice things up -- but this is just plain weird.

For some ungodly reason Jason Biggs and his wife got hooker for the American Pie actor's birthday -- and then decided to talk about it on national TV.

Biggs' wife Jenny Mollen appeared on The View this week to promote her recently penned a memoir I Like You Just the Way I Am, in which she describes a sexual encounter between the couple and a prostitute. There's a scene we have no desire to envision!

Guest host Candace Cameron Bure, who is a conservative Christian, didn't seem to find all the hooker talk amusing and criticized the part-time hooker lover on the show the next day. Defending his wife's honor (or is it dishonor?), Biggs took to the View's couches on Thursday to explain their side of the story.

"We are very open people, we are real people. My wife is amazing," said the Orange is the New Black star. "This is not a habitual thing on our part. We don't have a group of prostitutes who come in and out of our house on a regular basis." 

"I didn't have a good time in the end," he admitted. "It took three ladies over the course of three different days. Let's just say I didn't complete the mission. My wife found the whole thing to be quite hysterical even while it was happening. She was actually on the bed, watching, eating a bag of chips, laughing, so as you can imagine, I wasn't really performing to the best of my abilities. Also, said prostitute wasn't engaging with my wife the way I hoped she would and so it all kind of fell apart, and the rest is in the book." 

Umm that just sounds degrading if you ask us!

We're all for having pets, but snuggling up to a cat is a little different than sharing a bed with a snake ... er, right?

Willow Smith and her brother Jaden allow their pet snakes into their bedrooms, according to a source for Us Weekly. "Willow is obsessed with snakes," an insider tells the mag, adding that she "has 10 sleeping in her room" and "some aren't in cages!" Jaden "cuddles" with them in bed, and he even refers to his sister's pets as his "girlfriends."

Willow got her first boa constrictor in 2008 when she was 7 years old, and last year her mom Jada Pinkett Smith chatted with Redbook about how she finally caved in and let her daughter get a pet snake. "I've always loved snakes but was afraid of them," she said. "But Willow had wanted this one snake forever. She'd go into the pet store and pick it up and wrap it around her. I'd never touched a snake before, and I put out my hand, and Beauty [mimics the snake slithering up her arm]. I've been in love with her ever since. I said to Willow, 'You did Mommy a big favor. You helped me overcome a fear.'"

Well then! That doesn't seem so bad, right?

We never thought we'd see this sort of photo on Simon Cowell's Twitter, but here we are!

The other day the music mogul posted the above photo and wrote, "Bath Time!" and we can't see Simon's face, but we're sure he's just melting while looking at his adorable four-month-old son Eric.

Simon and girlfriend Lauren Silverman welcomed their little boy on Valentine's day this year, and just days after he was born, Simon posted some photos on Twitter and wrote, "Now you can see how very handsome little Eric is ... I never knew how much love and pride I would feel."

"I was born to be a dad," Simon gushed to his ex-girlfriend/pal Terri Seymour on Extra back in March. "I actually said to Lauren beforehand, 'What if I like the dogs more than him?' and she said, 'You're gonna be absolutely fine,' and then literally within seconds of him being born, I got it!"
