Mel Gibson used last night’s premiere of X -Men Origins: Wolverine in Los Angeles to premiere his new girlfriend, 39-year old Russian singer Oksana Grigorieva. The 53-year-old actor, who’s in the midst of a divorce from his wife of 28 years with whom he has seven children, has been linked to four different women named Oksana since his divorce was announced two weeks ago. At that time, the actor asked for privacy, a request at decided odds with showing up on the red carpet holding hands with a woman who is rumoured to be pregnant with his child. Then again, the actor, a devout, conservative Roman Catholic, is known for his erratic behaviour. He is also one of Hollywood’s richest stars: with a net worth rumored to be some US$900 million, Gibson’s divorce is expected to be one of Hollywood’s most expensive.
