Mel Gibson and Oksana Grigorieva have reportedly separated, but will continue to raise five-month-old daughter Lucia together.
The 'Braveheart' actor and the Russian singer reportedly "drifted apart" but have pledged to remain friends for the sake of their five-month-old daughter Lucia.
A source told People magazine: "They just drifted apart. They're both working hard on their careers and trying to raise a sweet baby together. They're still friends and they'll both raise Lucia together."
Despite reports insisting they are still on good terms, it has also been claimed 54-year-old Mel ended their relationship following a huge row.
According to National Enquirer magazine, 40-year-old Oksana accused her partner of "cheating" and "lashed out" over his reluctance to marry.
A source said: "After the row Mel told Oksana it was over."
Mel has previously admitted he didn't intend to marry the brunette beauty.
He said recently: "She'd make anyone a wonderful wife, but for the moment, she's a mother."
Mel has seven children with estranged wife Robyn, who filed for divorce last May.
Following the legal proceedings, it emerged the couple had been separated for some time and the actor was in a relationship with Oksana, who has 12-year-old son Alexander with ex-boyfriend Timothy Dalton.
