Watch! Bradley Cooper's Google Hangout On His American Hustle Perm

Even if you haven't seen American Hustle yet you'll have probably seen snaps of Bradley Cooper's immense 1970s perm.

This week the star - who is rumoured to be on the cusp of popping the question to his girlfriend Suki Waterhouse - told all about his barnet in a Google Hangout with the LA Times.

Turns out the film's hair department decided to manually curl his lid each morning - a process that took three hours! - rather than simply popping a wig on his head.

"We tried a lot of wigs, and I just looked like somebody from Three Stooges. So we curled it.

"They put this solution in it and we put 110 curlers in it and I sat underneath a heat lamp for 45 minutes... The whole thing was three hours.

"I've got to say, man, that I personally kinda fell in love with it. I definitely would try to stave off showering as long as I could because the minute the water touched it, it went limp. But I definitely went out with it at night."
