LOS ANGELES - Millions of girls love him, but Justin Bieber is definitely single.

The 16-year-old heartthrob from Stratford, Ont. tells The Associated Press he doesn't have a girlfriend and is just "hanging out" with a few girls.

The globe-trotting pop sensation says none of the relationships are serious.

Bieber is set to tour nationwide this summer to promote his new album, "My World 2.0."

He says he travels too much to take things too seriously, so he's just "being a teen, having fun."
