Tom Hanks and his wife Rita Wilson have become grandparents again.

Colin Hanks and his wife Samantha Bryant recently welcomed a baby girl named Charlotte, a sibling for their two-year-old daughter Olivia Jane.

The 34 year-old actor tells, "Ms. Charlotte Bryant Hanks has decided to join us. She's as happy and healthy as we are overjoyed and tired."

And the 35 year old jokes that his dad and stepmom are already looking forward to spending some quality time with the new addition, adding, "They cannot wait to just dote on this kid with every single fiber of their being. My wife and I are more than happy to give them our baby and say, 'Here, watch her while we take a nap!'"

The couple married in 2010.
