Jessica Alba continued her St. Bart's vacation on Sunday, showing her sexy curves and a little bit of sunburn in a tiny purple bandeau bikini.

The actress, who stars in the upcoming films Machete Kills and Sin City: A Dame to Kill For, is spending some adult time with husband Cash Warren and several friends, including Nicole Richie, who made the trip solo while husband Joel Madden is hard at work in Australia on their version of hit talent show The Voice.

The Good Charlotte singer won one of the country's TV Week Logie Awards for Most Popular New Male Talent on Sunday. The awards are basically the Australian equivalent of the Emmys.

"Love vacay with the homies!" she tweeted on Sunday with a photo of herself with all the ladies who made the trip with her.
