Penelope Cruz debuts growing pregnancy curves in black bikini

Penelope Cruz is proud of her pregnancy curves! The "Pirates of the Caribbean: On Stranger Tides" actress, who is expecting her second child with husband Javier Bardem, showed off her growing baby bump in a black bikini while vacationing in Barbados on March 5.

The Spanish star, 38, even took her son Leo, 2, for a dip in the ocean. Cruz and her family reportedly stayed in one of the Sandy Lane Hotel's two-bedroom Luxury Orchid Suites, which costs more than $1,000 per night.

Cruz's second pregnancy was first reported in early February, though she didn't confirm her happy news until weeks later during an interview with Spanish TV station TVE! The Academy Award winner said she was "tremendously happy and excited" to be giving her son a sibling.

Bardem's wife has said little about her life as a mother, though she made a rare exception when she appeared on the June 2011 cover of Vogue five months after Leo's birth. "I want my son -- and my kids if I have more -- to grow up in a way that is as anonymous as possible," Cruz told the magazine. "The fact that his father and I have chosen to do the work that we do doesn't give anybody the right to invade our privacy."
