Happy Birthday, Ryan Phillippe!

The "Lincoln Lawyer" actor turns 37 today, so we thought we'd throw together some of our favorite Phillippe photos.

From dating actress Amanda Seyfried, and having a baby girl, named Kai, with ex-girlfriend Alexis Knapp, it's been quite a busy year for the actor.

Take a trip down memory lane -- look and him and ex-wife Reese Witherspoon way back in 1999! -- and vote on your favorite photo below.
