Melbourne, Apr 29 : Putting all rumours to rest, Hollywood actor Mel Gibson has appeared with his Russian girlfriend Oksana Grigorieva for the first time in public at a premiere in Los Angeles.

Gibson and his lover went out together to attend the Los Angeles premiere of Hugh Jackman''s X-Men Origins: Wolverine, reports The Australian.

Grigorieva, who has a son with James Bond star Timothy Dalton, has been held responsible for breaking Gibson's 28 years of marriage with Robyn, after she was allegedly photographed embracing him in Costa Rica earlier this year.

He could lose half his 680million pounds fortune in the divorce.

Grigorieva has been reportedly living in one of Gibson''s Californian homes. (ANI)
