Singer Justin Bieber has a man crush on Ben Affleck because he thinks the "Batman v Superman: Dawn of Justice" actor has a "cool vibe".

The 21-year-old singer is a huge admirer of the 42-year-old actor because of his success and the way he conducts himself, reports femalefirst.co.uk.

When asked who his man crush is, Bieber named Affleck, adding: "I think his vibe is cool."

Bieber also admitted he wishes he had an alter-ego like Affleck's superhero character so he could just disappear when the attention from the paparazzi and the public got too much.

"I wish I had the Batman thing where people didn't know I was Bruce Wayne. Like I had a costume or something," he told Men's Health magazine.
