Much of the recent press around Dennis Quaid‘s children has centered on his new fraternal twins — but he won’t let anyone forget 15-year-old Jack Henry, his son with ex-wife Meg Ryan. Dennis tells USA Today and Dave Letterman that Jack is learning to drive — and that it’s somewhat scary!

Dennis, who says he’s gotten to know Daisy ‘a little bit,’ also has a special place in his heart for Kimberly Buffington Quaid, 36, and the sacrifices she has made to be his wife.

She now has her chance, as twins Zoe Grace and Thomas Boone are now a happy and healthy 3 months old. However, the typical twin dilemmas Dennis has spoken about previously are still an issue for the couple.

Calling the babies ‘T-Bone’ and ‘Z.G.,’ Dennis shared iPhone photos and discussed their developing personalities with both Dave and Regis and Kelly.

A health bonus has come with the birth of the twins and their ensuing medical issues — Dennis finally quit smoking.
