Pregnant Oksana threatens to leave Mel Gibson if he doesn't go to rehab

According to The National Inquirer, Octo-dad Mel Gibson and his Russian babe Oksana Grigorieva are already fighting because of Mel’s inability to control his appetite for booze.

“Oksana wants Mel to deal with his drinking on a long-term basis. Mel’s got a hair-trigger temper when he’s drunk, and Oksana insists she won’t stick around when he’s like that. She’s informed Mel that if he doesn’t go to rehab, she’ll bow out of the picture before they go any further.” an unnamed source says for the tabloid. The silver lining to this would be, according to the same spy, that Mel is desperately in love with the mother of his yet unborn child, so he’s already considering getting himself into rehab to put her mind at ease.

“Oksana thinks Mel will be less likely to cheat on her if he’s not out drinking. But she knows that Mel’s very stubborn and that it’s hard for him to stop drinking, especially now with all the changes in his life. The good thing is that Mel really loves Oksana, and he desperately wants to get his act together. He says he’s willing to do whatever she wants, but only time will tell if he stands by his words.” shares the spy.
