Mel Gibson  plaid jeans sunglasses

It certainly adds character ... especially since the tip looks like it was dipped in bleach!

On Wednesday night Mel Gibson was spotted at Los Angeles International Airport, and the 58-year-old star didn't look like he was in the best mood, but apparently he has every reason to celebrate! The news broke this week that his battery conviction for allegedly smacking ex Oksana Grigorieva in the mouth will be erased from his record ... woohoo!

Though Mel actually confessed to hitting Oksana in a sworn declaration in his custody case (he said, "I slapped Oksana one time with an open hand in an attempt to bring her back to reality"!), his legal team filed docs asking the judge to expunge his no contest plea, and it's all getting taken care of.

Gibson had been placed on three years probation, which was over in March, and there's a hearing set for a few weeks from now. The judge will reportedly allow Mel to withdraw his plea, the case will be dismissed and his criminal record will be cleared.
