Mel Gibson and Oksana Grigorieva call it quits

It’s turning out to be a bad day for couples news. First, Larry King and his wife Shawn Southwick file for divorce. Now we find out Mel Gibson (who just went through a divorce himself) and Oksana Grigorieva have split after over a year of dating.

The controversial actor and his Russian musician-singer girlfriend (make that ex-girlfriend) share a 5-month-old daughter.

“They just drifted apart,” a close friend of the couple tells People. “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.”

Right now Gibson is in Mexico filming “How I Spent My Summer Vacation” while Grigorieva has a charity concert in Russia next week.
