WATCH: Bradley Cooper Rock an Air Guitar on Jimmy Fallon

As I mentioned yesterday, Monday was Jenkintown native Bradley Cooper’s 40th birthday. To celebrate, he stopped by The Tonight Show Starring Jimmy Fallon to promote his latest flick, American Sniper, and to show off a musical talent many of us didn’t know he had: air guitar.

During his sit-down with Fallon, the host went over his list of accomplishments: acting, directing and … “a little musical talent.”

Cooper explains: “I’m glad you said that, because it’s very little. [Insert Fallon penis joke.] When I was a kid I had a lot of time on my hands and there’s this one song by Neil Young. I don’t know if everybody knows this [guitar solo], and I’m sort of proud that I know it. It’s just the guitar solo from ‘Down by the River.’ To air guitar to it is so meaningless … but I’d love to give you a little taste. It’s long. [Insert yet another Fallon penis joke.]”

Check out his performance below. Yes, he does the whole thing in a Carrot Top-looking afro wig that Fallon gave him for his birthday.
