Halle Berry filed for divorce from Olivier Martinez ... TMZ has learned. We're told Halle cited irreconcilable differences. As for money, we're told it's not an issue because the couple had a prenup. A source close to the couple tells us, "They have a personality difference." And the incident at LAX, where Olivier hit a guy with a car seat, exacerbated their conflicts. Olivier got sued for the incident last week and our sources say the couple argued about the suit, and it became a breaking point.
One source tells us the 2 year marriage went into a tailspin a week ago ... to the point each of them had it with the marriage, but Halle filed first.
Another source said, "They're just very, very different people. He's a very macho guy, and things just didn't jive."
The couple issued a joint statement ... "It is with a heavy heart that we have come to the decision to divorce. We move forward with love and respect for one another and the shared focus for what is best for our son. We wish each other nothing but happiness in life, and we hope that you respect our, and most importantly our children's privacy, as we go through this difficult period."
They have one child together, Maceo, who is 2 years old. Halle also has a daughter, Nahla, from a previous relationship with Gabriel Aubry.
Our sources say Halle is not asking for joint or primary custody, but rather what is in "the best interests of the child."
We're told the expectation on Halle's part is for a quick, non-contentious divorce.
