Kate Moss left The Ritz Carlton Hotel in Paris shortly after touching down for Paris Fashion Week.

The supermodel is arriving a few days late to the festivities -- Paris has missed you, Kate!

What do you think of Moss' floral-print jacket?

George Clooney, Jessica Alba, Clive Owen, Bono, Ewan McGregor, Idris Elba, Joe Jonas, Kristin Davis, Rob Lowe, Justin Long, Colin Farrell and Evan Rachel Wood have all united in a new PSA to fight a cause: the "F" word.

But, it might not be the "F" word you're thinking of. The PSA is for the ONE campaign, and it's against famine. "Famine is the real obscenity," says Bono in the vid.

Kristen Stewart has some choice relationship advice for you: Don't take crap from anyone!

The Twilight star graced the cover of Glamour's November issue, and she's opening up (big time!) about boys and the vampire franchise. She told the mag:

"Hmm...good relationship advice for me tends to be being honest and knowing yourself. Don't be an a**hole. That's my advice. Don't be mean. Don't take s**t. Dont settle."

Are you listening, Rob?

We don't think we've ever heard Kristen be so passionate about ... well, anything!

Is it any surprise that Rachel Zoe is taking in all the fashion she can while in France?

The stylist to the stars is in the City of Lights for Paris Fashion Week with hubby Rodger Berman, and the two attended the Valentino Spring-Summer 2012 Ready-To-Wear collection at the Espace Ephemere Tuileries.

Despite the fact that she packed THIRTEEN bags for the overseas trip, Rachel choose an all black ensemble for Tuesday's show. She opted for a long black button-down dress and floppy hat to the show.

Très chic!

Tiger Woods' mistress is a married woman!

Rachel Uchitel, best known for affairs with both the golfer and Bones star David Boreanz, wed former Penn State football player-turned-insurance broker Matt Hahn in Las Vegas over the weekend.

"We are really happy and feel extremely fortunate to have one another," she said in a statement.

The two obtained a marriage license Sunday night and filed it in a Clark County, Nev., court Monday morning at 8:58 a.m. They wed in front of 12 friends in Las Vegas' Little White Wedding Chapel.

Though the wedding was spontaneous, the San Francisco-based duo have been living together for about 10 months. In September, the 36-year-old even admitted to Page Six Magazine that she knew she wanted to marry him. "He's normal," she said. "He's not a famous person. I find him to be grounded and I'm totally going to marry him."

Congrats, Rachel and Matt!

Britney Spears and boyfriend Jason Trawick strolled the streets of Paris with her sons Sean Preston and Jayden James on Tuesday.

Jason seems to really care about the boys -- he's gone with Britney to their baseball games and more! So cute!

Brit accidentally called Jason her husband in a radio interview on Monday. Though Jason is rumored to be proposing soon, it hasn't happened yet, Brit!

Spears has been spending tons of time with her sons lately. They're touring Europe with her for Femme Fatale, and she even brought Sean Preston, 6, on stage in Hungary!

Jayden James, 4, and his big brother look more alike every day! Too cute.

LeAnn Rimes has just returned from North Carolina where she was interviewed by Pulitzer Prize-nominated poet Maya Angelou. The intimate sit-down took place at Angelou's home.

The 83-year-old legend is filming the new show The Celebration Table ... premiering in January on the Hallmark Channel. The upcoming project will focus on celebrities that have inspired Ms. Angelou over the years.

Leann tells X17online exclusively:

"We talked about forgiveness, marriage, children, poetry, music, food ... and drank great wine together. Her spirit is infectious. Meeting her changed my life. She's a walking angel and the wisest person I've ever met. She invited Eddie, the kids and me back to her home soon for a few days because she wants to cook for us."

The 29-year-old songstress also has a pelvic tattoo inspired by Ms. Angelou's famous poem about slavery that reads, "Still I Rise." LeAnn adds, "I'm happy to call her my friend and she calls me her daughter. What an honor."

A source close to the production says the poet believes the country singer has an "ancient soul":

"Maya has loved LeAnn since she was thirteen and thought she was an older black woman the first time she heard the song Blue. It wasn't until she saw a photo of LeAnn that she realized she was a little white girl."

The source adds, "Before the show was even given the greenlight, Maya knew she wanted to interview Leann to get to know her better."

22-year-old actress Alexis Knapp just sent out the first photo of her baby girl -- Ryan Phillippe's alleged daughter.

Though Phillippe (left) never publicly announced that he was the father, he did accompany Knapp to doctor's appointments and was at the hospital on July 6 for the birth of the little girl -- named Kailani.

Though the little lady has no father listed on her birth certificate, her full name declares Phillippe -- Kailani Merizalde Phillippe Knapp.

Her momma Tweeted with the pic: "I do declare you to be the prettiiiest lil girl in the whole wide world."

What do you think -- does she look like Ryan??

Either way, we commend Knapp for stepping up to the plate and being a good mom at a young age!
