The world has watched Dakota Fanning go from cutesy child star to acclaimed young actress and fashion plate, and now her little sister, Elle, is following in her older sibling's footsteps. The two talked with W magazine about fame, fashion, and finding furniture.

RPattz and Jimmy bro it up. Theo Wargo/NBCUniversal/Getty ImagesLeave it to funny guy Jimmy Fallon to get pouty Brit Robert Pattinson cracking wise and goofing off on his show. The "Twilight" heartthrob stopped by "Late Night With Jimmy Fallon" Thursday, where he bantered about the recent ceremony to immortalize prints of his hands and feet on the Hollywood Walk of Fame, his girlfriend and co-star Kristen Stewart's svelte physique, and more. The pair even got along so well that Fallon confessed that he roots for Team Edward -- under certain circumstances.

After their chat, the two donned plastic shields for a friendly game of bow and arrow darts. (Good idea, since I know a few people who'd be upset if Rob's face was damaged somehow.) But Twi-hards had nothing to worry about, because the actor was quite impressive in his play.

Justin Bieber sings songs of the season. -- James Whatling/Splash NewsHe's long been known for his hairdo, but from now on Justin Bieber will forever be associated with Christmas. You see, the Canadian heartthrob's new album, Under the Mistletoe, released November 1, is already doing quite well. MTV predicts the collection of holiday-themed original songs as well as some standards, including the Mariah Carey ditty "All I Want for Christmas Is You," will debut atop the latest edition of the Billboard 200 chart, with sales of more than 200,000. The Biebs also has just dropped a Claymation video for "Santa Claus is Coming to Town," which follows his clip for the sure-to-become-a-classic tune "Mistletoe."

Cementing his Father Christmas status, Bieber flipped the switch turning on festive lights at both the Westfield Shopping Centre and Westfield Stratford City malls in London on Monday. (Fun fact: Justin, 17, traveled the 12 miles between the two venues by helicopter!)

Kristen Stewart has now walked down the aisle in a dream wedding dress and had Bella's dream honeymoon in "Twilight Saga: Breaking Dawn, Part 1." But off-screen, Kristen says she still doesn't exactly feel like a "grown up."

The 21-year-old star talked to Parade.com about her highly anticipated love scene with Robert Pattinson and how Bella and Edward "hated each other" for the first time.

On the love scene the world is waiting for.

"The bed stuff was a little bit technical and weird. Every time I was off-camera, I was making goofy faces at Rob to make him laugh. I couldn't take it seriously. I had fun when we got romantic in the water though. It felt very spontaneous."

On her big walk down the aisle.

"I was so transcendentally weird that day. It was one of the last things that we shot in the movie, and I felt it all coming to an end. I was uber-aware; my nerves were so close to the surface of my skin. I had all of

Can we retire "Jersey Shore" to the pantheon of pop culture now? Just short of two years since its December 2009 debut, I'm ready to say the phenomenon has run its course thanks, in part, to MTV's decision to run four seasons back-to-back. After all, so much of the fun of watching the MTV hit in its early days was the shock of seeing that people actually live this way. Someone wears that to the club? She thinks skin that color looks good? They really dance like that? But by this point, Snooki, The Situation, Pauly D, and the rest of the gang have hooked up and brawled with everyone else in the house, and quite frankly, their behavior is getting a little old.

Madonna and Lola -- Jeff Vespa/VF11/WireImage.com Think you've got what it takes to be a Material Girl? Madonna and daughter Lourdes Leon, who goes by Lola, are looking for fresh faces to appear in the 2012 spring campaign for their junior clothing line for Macy's. Here's how their search will work: The company will have five casting calls at Macy's stores around the country, beginning November 2, where girls will be judged by a panel that includes "Fashion Police" star and Material Girl spokeswoman Kelly Osbourne. Next, fans of the line will vote on the 36 who make it through that phase via the Material Girl website beginning November 21. Finally, the top 10 will be flown to New York City to meet Madonna and, oh yes, compete for a chance to be the face of the line!

"This is not your standard model search," both Madonna and Lola were quoted as saying in their press release. "It's more about attitude. We are looking for a stylish, adventurous, creative free spirit. We're both looking forward to meeting the 10 finalists in New York in December."

Tyra Banks is proud of her debut book. Paul Zimmerman/Getty Images North AmericaTyra Banks is more than a supermodel -- she's a full-fledged media mogul, whose brand includes TV's "America's Next Top Model," fashion and beauty website TypeF.com, and now her first novel Modelland. The refreshing thing about the 37-year-old former talk show host is that, unlike some celebs, she's quick to credit her education with all the success she has today. In fact, after putting college on hold right after high school to try runway modeling in Paris, this year Tyra stunned everyone by enrolling at Harvard Business School, where she's scheduled to graduate in February.

The brainy beauty puts such an emphasis on education that she recently partnered with the non-profit organization Get Schooled, whose mission is to improve high school graduation rates, college readiness, and college completion rates. She surprised more than 400 students at the High School for Teaching and Professions in the Bronx, New York, with a celebration for raising their attendance four percent in two weeks as part of the Get Schooled national attendance challenge. After the fun, Tyra made time to talk to omg! about her high school years, her new book, and much more.

Snooki releases her latest literary treasure. Rob Kim/FilmMagicThe first time Snooki released a book back in January -- the novel A Shore Thing -- we all made jokes about how the "Jersey Shore" star had probably never read a book. But the joke is on us now, because the reality starlet is releasing a second tome, which means lots of us (was it you?!) forked over the cash for her literary debut. Snooki's Confessions of a Guidette, which details how to live life like she does -- and who wouldn't want that? -- hits store shelves today.
