Goldie Hawn had the love and support of her family tonight, including daughter Kate Hudson and soon-to-be son-in-law Matthew Bellamy, at the London launch of her namesake Hawn Foundation. Kate and Matthew are back in the UK following a glamorous appearance at this year's Vanity Fair Oscar bash. Kate caught up with pals Gwyneth Paltrow and Cameron Diaz when she wasn't snuggled up to Matthew in the dimly lit corners of the dance floor. During their stay in North America, Kate and Matthew also visited Mexico for a few days, where she worked on her tan in a sexy bikini.

The pair have been splitting their time between the West Coast and the UK, but for now they're back in Matthew's hometown while Muse continues recording their sixth album. They've been tweeting updates and sharing photos from their latest studio sessions.

Kristen Stewart got sexy in a short leopard-print dress in Paris today. She stepped out for the Louis Vuitton exhibit at the Musee des Arts Decoratifs, which showcases Marc Jacobs's 15 years of work at the fashion house. Kristen stopped by the designer's showroom on Monday after also popping up at Balenciaga's show last week. She wasn't the only famous face to show support for Marc ahead of the exhibit's public opening on Friday, since Robert Pattinson and Gwyneth Paltrow also came out for the event. Gwyneth arrived in France from London this morning, when she was spotted hopping on the Eurostar.

Gwyneth Paltrow posed in a sexy black suit at a special event for the Louis Vuitton — Marc Jacobs: The Exhibition in Paris this evening. She traveled to France via Eurostar from London this morning, though she was a little more dressed down in a cozy sweater for the trip. Gwyneth's timing meant that she missed the Louis Vuitton runway show earlier today, which was attended by Dianna Agron and Sarah Jessica Parker. SJP also stepped out for an early viewing of the exhibit, as did Kristen Stewart and Robert Pattinson. Kristen and Rob shared a romantic dinner date over the weekend, after Kristen attended the Balenciaga show solo on Friday.

Reese Witherspoon visited a friend's house in Brentwood earlier today. The actress is fresh off a weekend with husband Jim Toth and son Deacon Phillippe. Reese and Jim are approaching their one-year wedding anniversary on March 26. Her last project, This Means War, fell flat with audiences, but her next rumored big-screen attempt is already a hit based on the cast alone. Reese is reportedly in talks to share top billing with friends Gwyneth Paltrow, Cameron Diaz, and Beyoncé Knowles in the musical comedy One Hit Wonder. In 2005, Reese had major success with a musical when she earned her first best actress Oscar for portraying singer June Carter Cash in Walk the Line.
