While she seems not to have aged a day in the past 20 years, Halle Berry turned 45 on Sunday. The Oscar-winning actress celebrated with boyfriend Olivier Martinez and daughter Nahla outside her Malibu beach house, drinking cocktails and playing in the surf. Surrounded by friends, Berry showed off her incredibly toned body in a teeny, peach-colored bikini and a sarong.

Berry has been dating Martinez, the ex-boyfriend of Kylie Minogue, since they met on the set of Dark Tide last summer. Berry split with Nahla's father, French-Canadian model Gabriel Aubrey, in April of 2010. After a bitter custody battle that led to Berry's withdrawal from the film New Year's Day, the ex-couple eventually settled. "I'm so happy we've arrived at that place — because for her sake, this is the best way," Berry said in a statement at the time. "We both love her more than life."

In Dark Tide, due out later this year, Berry plays a diving instructor who returns to deep waters after a near-fatal shark attack. Directed by John Stockwell, the thriller also co-stars Ralph Brown.
