Mel Gibson has a little something to celebrate.

The actor, who recently pleaded no contest to misdemeanor battery charges stemming from incidents with ex-girlfriend Oksana Grigorieva, is a grandfather for the third time, PEOPLE reports.

Gibson's daughter Hannah gave birth to a son, and according to a friend, Mel "was overwhelmed with emotion."

"He gets that way around babies. ... He was overjoyed," the friend added.
