Happy birthday to the handsome Golden Globe-winning and Emmy-nominated actor Jon Hamm, who turns 43 today! Best known as dapper ad man Don Draper on AMC’s Mad Men, the former high-school football star is a versatile actor who’s equally comfortable doing comedy (like his incredibly funny and sleazy role in Bridesmaids, and Tina Fey’s clueless neighbor on 30 Rock) as he is drama (starring alongside Daniel Radcliffe in the recent Ovation mini-series A Young Doctor’s Notebook). He has also ventured into directing (he helmed two episodes of Mad Men) and along with actress Jennifer Westfeldt, his longtime love of over 16 years, he runs the production company Points West Pictures.

Besides Mad Men (which returns for its seventh season on April 13), Hamm will appear on the big screen in the Disney drama Million Dollar Arm and voice a role in the Despicable Me 2 sequel, The Minions, alongside Steve Carell and Sandra Bullock, out next year.

To celebrate the actor’s birthday, see how he’s changed through the years (though his hotness somehow stays the same)
