Kate Hudson sure knows how to rock a bikini!

The pregnant actress, who turns 32 on Tuesday, has never been shy about strutting her stuff in a two-piece!

Us Weekly first broke the news of Hudson's boob job in April 2010. A source told Us: "Kate [used to make] jokes about her boobs, but her chest has always been one of her biggest insecurities."

The mom-to-be is expecting her second child this summer, but her ever-expanding belly hasn't kept her away from the beach. She has one son--Ryder, 7--with ex-hubby Chris Robinson. This will be her first baby with her current beau, Matthew Bellamy.
