Kate Hudson made her first public appearance since an insider told Us Weekly that the actress, 31, underwent a small breast augmentation in late March.

Along with pals, she popped by the Coachella Music and Arts Festival on Sunday.

Hudson must have appreciated the fact that her chest looked fuller at the outside music celebration in Indio, Calif.

A source recently told Us: "Kate makes jokes about her boobs, but her chest has always been one of her biggest insecurities."
