Bradley Cooper turns 40 on Monday and is the ultimate American hunk

He first hit our screens as Jake in an episode of Sex and the City in 1999, and 15 years later that fresh-faced hunk Bradley Cooper is turning 40 on Monday!

From 2005’s Wedding Crashers to 2009’s He’s Just Not That Into You and The Hangover, how could you not fall for those dreamy blue eyes?

So it’s no wonder he got together with his Guardians of the Galaxy co-star, the gorgeous Zoe Saldana, for just over one year.

He was also Renee Zellweger‘s other half for two years from 2009 and before that was rumoured to have briefly dated Jennifer Aniston and was married to actress Jennifer Esposito from late 2006 to May 2007, when she filed for divorce.

Nowadays though, he’s enjoying a relationship with British model Suki Waterhouse and even when he’s onscreen he always seems to have a beauty by his side.

Take his American Hustle and Silver Linings Playbook co-star Jennifer Lawrence for instance.

Aside from having a stunning girl on his arm, Philadelphia, Pennsylvania-born Bradley is likely to be celebrating his best birthday yet as his latest movie hit, American Sniper, reached no.1 at the US box office at the end of 2014.

Aside from being nominated for an Oscar, other achievements through his career have included his People Magazine Sexiest Man Alive accolade from 2011.

And his look has definitely transformed since his screen debut in the 90s. Check out how he’s gone from smooth-faced and slender with short hair, to flowing locks, to sexy stubble and buff beach body.
