Less than three weeks after his wife of nearly 30-years filed for divorce, Mel Gibson stepped out with his girlfriend for the Los Angeles premiere of X-Men Origins: Wolverine.

Gibson, 53, walked the red carpet holding hands with 39-year-old Russian singer Oksana Grigorieva, who is signed to his record label Icon Records.

“They came in quietly and as under-the-radar as they could and they were pretty low-key. Mel seemed very comfortable,” says a source.

Gibson’s rep told People magazine, “Mel has been single for almost three years and it’s nice to see him getting out and enjoying himself.”

Robyn Moore filed for divorce from Gibson in early April. Sources close to the couple later revealed they had been separated for nearly 3 years but remain friends. Gibson and Moore have 7 children ranging in age from 28 to 9.
