finally went public with his Russian singer girlfriend , 39, at the X-Men Origins: Wolverine premiere in LA Tuesday night. They’ve been living in secrecy in Costa Rica or wherever.

The couple held hands as they walked the carpet before taking a seat at the screening at Grauman’s Chinese Theatre in Hollywood.

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

“Mel has been single for almost three years and it’s nice to see him getting out and enjoying himself,” his rep tells PEOPLE exclusively.

I thought Mel Gibson was dating a hot Russion popstar, but apparently those were “erroneous” reports with “erroneous” pictures. I don’t even know what that word means. I just put it in there because it sounded cool. Maybe these big words will get me invited to a red carpet event one day. And on that day, I may even eat an erroneous pizza. Am I doing this right?
