Rachel Bilson lent her support to a fellow celebrity designer last night, turning out to attend the launch of Amber Valletta for Monrow at Ron Herman in LA. The girls posed for photos side by side, before Rachel ventured off to browse the collection. Rachel is familiar with fashion events, but she's also gearing up for a return to acting with her upcoming stint on How I Met Your Mother. Amber, meanwhile, has been focusing on building her career after modeling, and who better to ask about that than her good friend Kate Moss?

New Moon is here! We've been gearing up for weeks with slideshows, videos, interviews and of course thousands of photos — even a brand-new Twilight faceoff — but now the movie is out. Many of you have already rushed out to see it and we can't wait to hear what you think, and here's our thoughts. Watch our PopSugar New Moon Review now!

The cast of The Romantics was back to work yesterday as filming continued on the Long Island set. Suri wasn't around to keep the cast entertained with her high heels or limbo skills, but everyone looked casual compared to the big wedding scene they filmed earlier this week. While Katie and Josh keep it rolling on the set, their significant others have been keeping busy with their own projects. Fergie joined the Victoria's Secret Angels for a performance with the Black Eyed Peas yesterday while Tom was busy jetting off to Europe where he joined costar Cameron Diaz on the Austrian set of Knight & Day.

Zac Efron arrived in London earlier this week to promote Me & Orson Welles, and he was busy yesterday and today doing a variety of interviews. He made an appearance last night at the Notting Hill Gate cinema for a question and answer session with fans, and PopSugar UK was there to chat with him — check out their interview! He was out again this morning for a stop by the Capitol Radio studios. He kicked off his trip to England with a premiere on Wednesday alongside costar Claire Danes, as Zac's press tour goes into full swing.
