This is seriously cute ... Halle Berry's boyfriend Olivier Martinez playing and laughing on the beach with Halle's daughter Nahla. From the looks of it, you'd think he was her biological father!

These two obviously have a tight bond which is good, since Nahla spends most of her time in Halle's care. The actress and Nahla's father, model Gabriel Aubry, fought an extended custody battle after splitting in April of last year. It was until April of this year that the two finally reached a legal agreement concerning the custody of the daughter - the terms of which weren't released.

Halle commented to Extra TV: "Our issues were never about fighting for her. We both know a child needs both her parents. But what I want to say about it is sometimes, as a couple, you reach an impasse. We need a court and a judge to help us work out some of the delicate issues, and I'm so happy we've arrived at that place—because for her sake, this is the best way."

Seems like Nahla has two good dads in her life!
