It was a beautiful Sunday in LA where lots of familiar faces came out for the A Time For Heroes Celebrity Carnival to benefit the Elizabeth Glaser Pediatric AIDS Foundation. Among the all-stars out for the great event were adorable (and tiny!) new parents Nicole Richie and Joel Madden along with Courteney Cox and ever-quirky David Arquette. Mischa looked every bit the flower child in her butterfly wings while all the ladies (and ugh Heidi and Spencer) of
The Hills happily posed for the cameras.

This week, Law & Order: SVU announced something of a casting coup, saying it had gotten
Robin Williams to guest-star on the show's 200th episode on April 29. It was already a big week for news about cameo appearances, anyway, as we're now counting down the days till

Sarah Silverman's hilarious video confessing in song to her chat-show host boyfriend Jimmy Kimmel that she's "f*cking Matt Damon"?

Keri Russell showed off her amazing post-baby body getting giggly with Jonathan Rhys-Meyers at the red carpet premiere of their new movie
August Rush in NYC last night. Their costars Terrence Howard, Robin Williams and Freddie Highmore (Kate Winslet's adorable son in Finding Neverland) also came out for the screening and kept cozy despite the chilly NYC night. In the movie, Keri and Jonathan play a pair of musicians who are forced to give up a baby for adoption after a one night stand, and their son uses his musical gift to find his way back to them after 11 years.

Sometimes all it takes are a few good words to get you moving...
