This past year was a busy one for Reynolds: he starred in two big-screen films, Green Lantern and The Change-Up, he's currently in Boston shooting his upcoming R.I.P.D. in Boston, and he divorced from his wife of two years, Scarlett Johansson, in July.
Since then, he's been rumored as having quite a number of flings: Charlize Theron, his Proposal co-star Sandra Bullock, Olivia Wilde and most recently, Gossip Girl actress Blake Lively.
No word on what the actor has in store for his birthday, but one thing is for sure -- he's in good company.
The hot-bodied star was spotted leaving his Boston apartment with Lively (his Green Lantern co-star), early Saturday morning. Rumors have been buzzing about the pair since they were spotted in an affectionate embrace at Beantown's South Station earlier this month.
