Michelle Monaghan is an actress, and while she is not as famous as most of my Celebrity Birthday choices, I picked her because, quite frankly, I am in love with her. I always find her a pleasure to watch, from Unfaithful, “Boston Public”, and Mr. and Mrs. Smith to Mission: Impossible III, Gone Baby Gone, Eagle Eye, and Due Date. I am really looking forward to next week’s release of Source Code, and Michelle is in that, too, so that’s definitely a bonus!
