Katie Holmes led the crowd in a round of applause as husband Tom Cruise was presented with the Simon Wiesenthal Center Humanitarian Award at the organization's annual tribute dinner in Beverly Hills. (Cruise stayed mum when asked if he and Holmes will help the Beckhams entertain Prince William and Kate Middleton during their visit to California.) In New York City, Jennifer Aniston turned up the heat when she signed bottles of her eponymous fragrance at Sephora, Donna Karan and Susan Sarandon honored outstanding moms, and The Twilight Saga's Kellan Lutz showed off his sensitive side, taking in a performance of the off-Broadway play Love, Loss and What I Wore. Meanwhile Down Under, Reese Witherspoon and Robert Pattinson got up close and personal with a trained pachyderm while promoting the Australian release of Water for Elephants.
