Justin Bieber has opened up on his 'man crush'.

The singer was asked by Men's Health magazine who he has high levels of admiration for.

The Canadian picked actor Ben Affleck, adding:

"His vibe is cool."

Affleck is due to play the leading role in the next Batman movie and Bieber said in the same interview:

"I wish I had the Batman thing where people didn't know I was Bruce Wayne.

"Like I had a costume or something."

The April issue of Men's Health will go on sale in the US from March 10.
