More from the party hats department: Avril Lavigne threw hubby Deryck Whibley a surprise 29th birthday barbecue at their Los Angeles home. "Deryck seemed totally surprised and Avril hugged and kissed him after the big reveal," a source tells us. "The two held hands and were touchy and affectionate throughout the party." Meanwhile, 30 guests (including Katy Perry) drank Belvedere IX cocktails and enjoyed light bites – all to a punk-rock soundtrack.
In Austin for South by Southwest, Drew Barrymore rocked out in the front row as The Airborne Toxic Event played a showcase at Aces Lounge – and the actress was singing along to every song, a source says. The actress also stopped by the Nintendo Lounge for a beer with friends. Also spotted at SXSW: Rocker Perry Farrell, pumping his fist in the VIP section at Stubb's Bar-B-Q for Metallica's secret show for their video game, Guitar Hero: Metallica.
Anne Hathaway, catching the risqué puppet show "Puppet Up! – Uncensored" at the Avalon Hollywood with friends. The smiling actress skipped the booze for cranberry juice, and "was in a really great mood: friendly, very polite and getting a kick out of the show," an onlooker says.
Seth Rogen and girlfriend Lauren Miller, enjoying a sweet ending to their steak dinner at Morton's The Steakhouse in Beverly Hills: a piece of New York cheesecake. Before sitting, Rogen grabbed a Shirley Temple in the bar.
