So much star power!

The A-listers were out in full force and in their finest threads on Thursday night as the New York City Ballet held their 2013 Fall Gala at Lincoln Center’s David H. Koch Theater in Manhattan.

Celebs such as Natalie Portmant, Sarah Jessica Parker and even rapper 50 Cent graced the red carpet at star studded event.

It was also a premiere of sorts for Portman's choreographer husband Benjamin Millepied as the future director of dance at the Paris Opera Ballet debuted his latest work at the gala.

Wasting no time after her whirlwind trip to Las Vegas, Khloe Kardashian kept a cool facade on Thursday, when the 29-year-old refused to answer questions when asked about whether or not she would be divorcing her estranged husband, Lamar Odom.

On Thursday morning, Khloe, along with sister Kourtney, shot a segment for Keeping Up with the Kardashians at the their store on Melrose. In and out of Vegas in the blink of an eye, Kourt and Khloe were in Sin City to make a few appearances to promote their clothing line, Kardashian Kollection.

"5 hour trip to Sin City for kardashiankollection back to LaLa Land," Khloe tweeted on Wednesday.

Looks like Khloe is keeping upbeat (at least outwardly) despite some major marital woes, although there are definite signs of strife on social media. On Wednesday, the tallest Kardashian took a mini break from snapping selfies to post an Instagram picture of a masked woman with the mysterious quote, "She smiles to mask the pain in her heart. She laughs to conceal the tears in her eyes."

Yikes! We guess we know that behind those sultry selfies lies an unhappy camper ...

We wonder what they were doing?!

Simon Cowell and his pregnant girlfriend Lauren Silverman stopped by a lawyer's office in N.Y.C. this morning, and we're dying to know the reason for the visit!

Could they be hashing out a prenuptial agreement in order to tie the knot before their baby boy arrives?

We never thought we would say the words marriage and Simon Cowell in the same sentence, but based on how much he has been gushing about his happiness lately, we're starting to think he's going to make an honest woman out of his baby mama!

"I love Lauren and I love that we're having a baby. I didn't think it was going to happen. But you have to deal with it as a man: Let it happen naturally. I am the happiest now than I have been in a long time," the music mogul recently told People.

If the King of Mean marries, George Clooney will be Hollywood's last remaining self-professed bachelor!

Well, it's not like she actually works at Dash, but you know what we mean...

On Thursday morning Kourtney shot a segment for the family's reality show at the their store on Melrose, and Kourt and Khloe just got back from Las Vegas after making a few appearances to promote their clothing line.

"5 hour trip to Sin City for kardashiankollection back to LaLa Land," Khloe tweeted, and prior to that she posted a blog about "upgrading [her] wardrobe for fall," but it was really just a blurb talking up the ladies' handbag line. Are they ever NOT trying to sell us something?

Reese Witherspoon is getting toned! Looking happy as can be, the Oscar winner left her favorite gym, Burn 60, after working out with friends in Brentwood, Calif., on Thursday.

According to their website, Burn 60 is a "fun, effective, fast-paced, 60-minute workout for all fitness levels." Whatever the workout is -- Reese has never looked better

Outfitted in a black hoodie, leggings and colorful Asics, the sweaty star looked like she had a great time with friends kicking her butt into high gear. The 37-year-old has become quite the gym rat, and recently debuted her slimmer figure at the Devil's Knot premiere during the Toronto International Film Festival.

Devil's Knot, which hits theaters later this year, is based on the true story of three teenagers who were falsely convicted of killing two 8-year-old boys in Tennessee. The trio, known as the West Memphis 3, were released two years ago after spending 18 years behind bars. Reese plays Pam Hobbs, the mother of victim Stevie Branch, and Colin Firth also stars in the movie as Ronald Lax, a private investigator who represented one of the accused teens.

Sean "Diddy" Combs attended the Vallure Vodka launch event at Hakkasan in Beverly Hills, and the rapper rocked an outfit that looks like it came straight from Justin Bieber's closet! From the dropped crotch to the leather accents, this isn't what we'd normally expect Diddles to wear...

Other celebs at the event included B.J. Novak, Ellen Pompeo, Busta Rhymes and Samantha Ronson, who seemed confused/annoyed as to why we were taking her photo:



Talk about an odd crowd!

We wish this was true, because they would be an adorable couple!

Reports surfaced last week that Watch What Happens Live! host Andy Cohen was engaged to former New York Rangers hockey player Sean Avery, but the Bravo executive set the record straight yesterday that the rumors were completely false, although he wishes they weren't!

"Sean Avery is straight. Do you understand that? So a gay guy and a straight guy should be able to be friends, without you asking me if we're engaged. Right?" he told TMZ.

"He's very, very straight. Listen I'd be happy if Sean and I were banging... but it's not [happening]," he added.

And there you have it folks!

This looks like the most drama-filled season yet!

The trailer for season 4 of Real Housewives of Beverly Hills was just released, and let's just say adding some new ladies to the mix is a recipe for cat fights!

Former regulars Adrienne Maloof and Taylor Armstrong are replaced by Former Miss Puerto Rico Joyce Giraud de Ohoven and British actress-turned-designer Carlton Gebbia.

Brandi Glanville must have been angling for more camera time, because she clashes with one and crushes on the other!

"Carlton is a bad-ass. She's hot, I like her," she declares as they show the two sharing a passionate kiss in a hot tub.

Meanwhile, Eddie Cibrian's ex isn't exactly enamored with the former pageant queen. After being labeled a "bully", the Drinking & Tweeting author has some choice words for her new nemesis.

"If I was a bully I would have knocked your f**king teeth out by now," she screams at the brunette beauty.

Some other highlights to look forward to?

Former besties Brandi and Lisa Vanderpump are on the outs, Kyle Richard's husband Mauricio is accused of cheating, and Yolanda Foster weathers a health crisis.

Let the hair extensions fly!
