The front row at today's Mulberry Where The Wild Things Are-inspired show during Fall Fashion Week, held at Claridge's Hotel, was star-studded. Michelle Williams held court in the middle of a celebrity array that included Lizzy Olsen, singer Lana Del Rey, and two of the female leads from Downton Abbey, Michelle Dockery and Laura Carmichael — are you excited for the Downton Abbey season finale this evening?

Holding down things on the guy side was Thor and War Horse actor Tom Hiddleston, who was lucky enough to catch a few minutes with Michelle Williams and pose for photos with an arm around Michelle Dockery. After checking out what creative director Emma Hill sent down the runway, the group reconvened for a special dinner at the Savile Club. Chef Tom Aikens presided over an all-British meal. Lana Del Rey is the night's performer, and also had the recent honor of Mulberry naming their "Del Rey" bag after her.

Shirtless Channing Tatum and Jonah Hill made a splash on Sydney's world famous Bondi Beach today. The 21 Jump Street stars are kicking off their international promotional tour and have plans to host a screening for their Australian fans tomorrow night. The film, opening March 16, is already getting rave reviews from critics in the States, and it's really no surprising since both Channing and Jonah are at the top of their game.

Channing's coming off The Vow's major box office success. The film earned the number one spot last weekend, broke records on Valentine's Day, and is currently poised to take the top slot for the second weekend in a row. Jonah, on the other hand, recently earned his first Oscar nomination for his supporting role in Moneyball — be sure to fill out our 2012 Oscars ballot for a chance to win an iPad 2 16GB WiFi and Prada case! The guys seem to be enjoying their trip Down Under, but they'll be back in LA in just a few short days so Jonah can prep for the Feb. 26 Academy Awards celebration.

Jessica Alba and Cash Warren found a cozy patch of grass at an LA park yesterday and spent the afternoon relaxing with their daughters Honor and Haven. The girls were all dressed in navy for the family outing, though earlier in the week Jessica modeled a sexy turquoise dress during a Fashion Week appearance. Jessica was seated in the front row at Michael Kors's Fall 2012 presentation with fellow actresses Amber Heard, Paula Patton, Debra Messing, and Angelica Houston. Fashion followers, stylists, and designers moved on to London for the next crop of shows, but it looks like Jessica's happy to sit this round out in order to spend more time with Cash and the girls.

London Fashion Week kicked off yesterday with a magical presentation from Stella McCartney. Many of Stella's friends came out to see her Winter 2012 London Evening Collection, which began with a vegetarian dinner for the likes of Kate Moss, Jamie Hince, and photographer Mario Testino. Models were seated at the tables with guests, and following the meal, excused themselves to perform a choreographed dance routine in Stella's designs. The fun didn't stop there for one guest. Alexa Chung was called to the stage by a magician who hypnotized her and then levitated her body above swords! Stella herself got in on the games by performing a card trick.

Rihanna wore a sexy dress for the party as well. After posing for photos on the red carpet in a sexy jewel-toned gown, she met up inside with Kayne West. Rihanna turns 24 on Monday, and started her celebrating last week at a private post-Grammy party in LA. Another young star, Shailene Woodley, mingled with Vogue editor Anna Wintour, fashion icon Twiggy, and actress Minnie Driver. Shailene doesn't have an Oscar dress yet, but said at the bash, "I have no idea what to wear, so yes, I’m always looking for red carpet dresses."

Robert Pattinson returned to LA last night following a short stay in Germany. Rob screened his upcoming drama, Bel Ami, at the Berlin Film with costars Holliday Grainger and Christina Ricci. During a press conference Rob described his character as "completely unrepentant" and said he had "quite fun playing" a womanizing social climber. He charms a string of leading ladies on the big screen, but in real life critics haven't been impressed with Bel Ami, which opens March 2.
