Olivier Martinez is preparing for the biggest role of his life… Dad.

The 47-year-old half-Spanish actor and his actress fiancé Halle Berry are expecting their first child together.

Berry, 46, has a 5-year-old daughter, Nahla, from her previous relationship with Gabriel Aubry.

Berry and Martinez started dating after filming the thriller Dark Tide together in 2010. He proposed the following year over the holidays and confirmed their engagement last March.

Martinez previously had a longtime relationship with Australian singer Kylie Minogue.

His credits include Cybergeddon, Blood and Chocolate, Unfaithful and S.W.A.T.
