It was practically impossible to tell Mary-Kate and Ashley Olsen apart in Paris on Saturday night!

The two looked more identical than ever now that both are back to blonde, and their long, black get-ups were super similar!

The sisters are in Paris for Fashion Week. We snapped them as they headed from their hotel to Kanye West's show.

But Mary-Kate and Ashley aren't just attending -- the successful young designers debuted the new handbag collection for their The Row label with a cocktail soiree at the Montaigne Market in Paris.

The collection has already sold out of its alligator backpack -- which retails at an eye-popping $39,000 (see the black bag in our picture above.)

Designer Christian Louboutin attended the party, where he told reporters he feels like a "godfather" to the twins.

Wow. And we thought his scenes in American Pie were graphic.

Actor Jason Biggs' wife, actress Jenny Mollen, just wrote a steamy blog post for Playboy about the time she and Biggs hired a Las Vegas hooker to spend the night with them.

The couple was only about a year into their marriage at that point, she says, but was looking to spice things up.

Mollen details the whole evening -- and it's a bit too graphic for us to post here! But here's an excerpt, in which Mollen talks about the stripper telling her and Biggs how to stay comfortable during the encounter.

"I felt like I was in driver’s ed. and I loved it! This is exactly the type of information I wanted to be armed with. My husband, however, didn’t have the same reaction. With sweaty palms, clearly a bi -product of all the newly discovered potential for failure, he undressed and sat on the bed. Keisha instructed me to do the same."

Rumors surfaced Thursday that The Real Housewives of New Jersey's Jacqueline Laurita had quit the Bravo show last week, in the middle of taping for Season Four. She Tweeted some disturbing thoughts on Saturday:

"This show is a curse! ... I'm losing it.This is what all this negativity I'm surrounded w/does 2me."

It seems Teresa Giudice (right) is the catalyst behind Laurita's decision.

Laurita Tweeted on Saturday: "Teresa put out an article that I ... threatened to release those pictures and I didn't! ... Teresa is scum!"

The "pictures" are photos of Joe Giudice, Teresa's husband, out with another woman. They surfaced online last week. Laurita Tweeted texts she'd sent to Teresa:

"Tell your husband I am NOT getting into your business and NOT to threaten my husband! I didn’t take or release those pictures … just wanted to give you both a heads up … Don’t shoot the messenger!”

Bravo came under fire in August when Russell Armstrong, husband of Real Housewives of Beverly Hills' Taylor Armstrong, committed suicide. His family, friends and lawyer cited the show as a major source of stress for Russell, and Taylor told Dr. Phil McGraw that Russell might still be alive if they hadn't done the show.

Laurita also said Giudice was "scum" for spreading rumors that Giduice's sister-in-law, and fellow castmate, Melissa Gorga, was a stripper. Keep reading for Gorga's response.

Modern Family star Sofia Vergara got dinner at Katsuya in Hollywood on Saturday night, where she wowed longtime boyfriend Nick Loeb with her ravishing red lips!

The night before, Vergara headed to castmate Eric Stonestreet's birthday party at the Sunset Towers hotel in West Hollywood, where she munched on donuts and cupcakes!

How does she maintain that fab body and still eat sweets?? In a word: jealous!

Pete Wentz and new girlfriend Meagan Camper couldn't stop smiling at each other Saturday night!

The couple hit The Roosevelt hotel and nightclub in Hollywood, then walked down the street to grab some late-night pizza. It's always good to eat up after a night of partying!

It's nice to see Wentz, 32, happy again after his split from wifey Ashlee Simpson in February! Meagan wore Pete's hat, and inside the restaurant they fed each other -- watch in our video below!

While in Paris for Fashion Week, Glee's Lea Michele took a day trip to the famous Versailles palace on Saturday, and looked classically Parisian in black and white!

The starlet Tweeted: "It's 80 degrees and sunny today here and the gardens of Versailles are beautiful.."

And though she's only 25, did Lea get baby fever in that heat? She cuddled a cutie throughout the day (see below)!

The actress stayed Friday to Sunday in the City of Lights -- how glamorous to jet in and out of Paris just for the weekend!

Michele, who was traveling with makeup artist pal Melanie Inglessis, met Karl Lagerfeld for the first time at this presentation for Hogan, drank champagne at the Louvre museum, and, of course, ate crepes!

Anderson Cooper's new daytime talk show has only been on the air for three weeks, but it's already dealing with a major problem.

A teenager is in a coma after the show's producers allegedly encouraged him to record the "crazy stuff" he did. The home footage would have been for an episode covering how the adolescent mind works.

The teen filmed himself skateboarding and fell, suffering a serious injury to his head. He is now in a coma.

The episode will not be broadcast. Said the show in a statement:

"As part of our routine process, we ask guests for video footage and photos. We did not provide the family with a camera. On the morning that they were supposed to travel to NYC, we learned that the teen had been injured. We are very concerned about him, and are thinking of him and his family at this time."

Cooper said in a personal statement on Saturday evening:

"I was very saddened to hear the news of this accident, and want to express my deepest concerns for the teenager who was injured. I take this situation seriously, and my thoughts and prayers for his health, well-being and recovery are with him and his family."

Journey guitarist Neal Schon gave an electric guitar serenade to ladylove Michaele Salahi at his band's concert in Denver on Saturday night.

Schon played "Happy Birthday" to Salahi, who gave a wave to the crowd from the side of the stage. Then, of course, they shared a kiss.

Michaele's soon-to-be ex husband, Tareq, is allegedly trying to get his own dating reality show. He's been spotted hanging out with New York madams and busty blondes in recent weeks.
