Jake Gyllenhaal is 38 today (December 19)! Since 2001's Donny Darko, the Hollywood hunk has been lighting up our cinemas - and our hearts - with those puppy-dog eyes and irrepressible charm in everything from Brokeback Mountain to Southpaw.
To celebrate, we've brought together 38 of his hottest moments on and off screen. Think of them like birthday candles on a cake - but with more nudity.
Many happy returns Jake!
