Grandpa Gump: Tom Hanks' Son Colin Welcomes First Child

Tom Hanks has been a bosom buddy, a castaway, and even sleepless in Seattle: on Tuesday, he became a grandpa for the first time, RadarOnline.com has learned.

Colin Hanks, the 33-year-old son of the A-lister and the late Samantha Lewes, became a father Tuesday, as his wife Samantha Bryant delivered their baby daughter Olivia Jane in Los Angeles.

"The family is home and everyone's happy and healthy," an insider told People.

The Orange County star married Bryant in May 2010.
