The battle between Russian musician Oksana Grigorieva and her ex-lover Mel Gibson is about to get even uglier thanks to a potentially nasty courtroom confrontation between two Hollywood stars. Oksana claims another ex of hers, former James Bond star Timothy Dalton will testify against the Mad Max star Mel Gibson if called upon. Apparently Dalton noticed the singer was bruised which led to her confessing that Gibson had struck and choked her.
