Most Wanted/Flynet

Given their rocky start in life, that 11-month-old twins Thomas Boone and Zoe Grace are poised to celebrate their first birthdays next month must feel a little like winning the Super Bowl for parents Dennis Quaid and Kimberly Buffington Quaid. So when Dennis was asked during a Wednesday appearance on The Late Show with David Letterman how he plans to mark the occasion, his answer should come as no surprise: "We’re going to Disneyland!" The 54-year-old actor harbors no illusions about the twins’ ability to appreciate the experience, however.

Along for all those rides will be the twins’ big brother Jack Henry, 16, from Dennis’ previous marriage to actress Meg Ryan. Jack — having recently obtained his license — is an "excellent driver," Dennis shared.

Dennis’ new movie, The Express, is in theaters October 10th.
