• Russell Crowe, toting his son Charlie, 3, around Sydney, Australia as the father-son pair went on a shopping expedition. On the agenda? Picking out a dress for Crowe's wife, Danielle Spencer.

• At Hollywood lounge Les Deux, Paris Hilton, arriving just in front of her recent party pal Adrian Grenier, following a quick dinner together at Parc. (The Entourage star has been hanging with the heiress as he continues to work on a documentary about fame and the paparazzi.) True to form, Hilton bounced through the door with paparazzi following close behind – before planting herself at a table with sister Nicky and her boyfriend David Katzenberg. Also at Les Deux: Dave Navarro, sitting at a table with Jenna Jameson.

• Before hitting the clubs, Hilton and Grenier attended an art opening for Los Angeles painter Louis Carreon at Uncle Buck's, a Hollywood gallery. Carreon, a one-time Los Angeles party hopper, attracted plenty of celebrity guests to his exhibition "For the Love of Honey," including Kevin Connolly and Ricki Lake. "I paint to touch the populace in ways of love and lust," he told us. Hilton, meanwhile, did more than just appreciate the art: She took some home. "I've been friends with Louis a long time so it's cool that he made a painting for me."

• In Las Vegas, rapper Xzibit, surprising patrons at MOON Nightclub with an impromptu two-song performance. The former Pimp My Ride host partied on the dancefloor and kept company with a crew of NBA players in a private booth before wowing the crowd with his lyrical skills.

• Rumer Willis, smiling as she partied at Hollywood bar and lounge Green Door. The House Bunny actress hung out with some friends at a table across from Danny Masterson, who made it a low-key night out with the guys. And the Green Door wasn't Willis's first stop: Earlier that evening, she and friends attempted to hit up new hot spot Crimson but, alas, were turned away. Why? They were underage. Also partying at Green Door: Michelle Rodriguez, arriving after midnight with her posse.
