A photo of Oksana Grigorieva with a black eye, alleged to have been caused by Mel Gibson after an altercation, is making the round online. It is posted at RadarOnline exclusively.

The close-up shot, which shows the Russian singer, 40, with deep bruises around her left eye, was reportedly taken after she and Gibson, 54, had gotten into a heated argument in January, according to RadarOnline, which posted the photo.

Meanwhile, Mel’s camp is firing back:

Sources close to Gibson have denied the allegation, saying he was trying to stop his ex from shaking their 9-month-old daughter Lucia “like a ragdoll.”

This all-out celebrity fight to the death is going to get a lot worse before it gets better.
