Jesica Alba ( Caught in the Act!)

• Jessica Alba fêted her hubby Cash Warren with a lively birthday bash at Spin Hollywood inside the Mondrian Hotel. The group enjoyed cocktails and plenty of ping pong – as well as tunes by DJ Jedi. Warren, who turned 32, also got a ping pong-themed birthday cake and the well wishes of pals like Baron Davis and Benji Madden.

• Meanwhile in San Diego, Jessica Biel celebrated a pal's 30th birthday at Fluxx. Biel kept a low profile at their VIP table inside the nightclub, staying covered up with a scarf while sipping on her vodka soda as her friends hit the dance floor.
