Mel Gibson becomes grandfather

Los Angeles: Hollywood star Mel Gibson has become a grandfather for the third time.

His daughter Hannah gave birth to a baby boy on Saturday night, making Gibson, 55, a grandfather for the third time. Hannah and her husband, blues singer Kenny Wayne, already have a son and a daughter.

The actor, who pleaded no contest to a misdemeanour`s battery charge in court to ex-girlfriend Oksana Grigorieva, spent the weekend celebrating the birth of his third grandchild, the People reported.

"He was overwhelmed with emotion. He gets that way around babies. He was overjoyed," a friend said about his daughter Hannah`s baby boy.

The 55-year-old star also spends his time with one-year-old daughter Lucia, who is the bone of contention between him and Grigorieva.

"He always has a great time with her," the friend added.

Gibson was sentenced last week to 36 months of probation and 16 hours off community service stemming from a battery charge after he attacked Grigorieva last January.

The 44-year-old singer is said to be considering filing a civil suit against Gibson for battery , emotional distress and defamation but the actor has reportedly told friends he will file a counter suit if she does.
