"Louis is happy and very excited about becoming a dad and he thinks Briana will be an amazing mother. It was a surprise at first, but he and Briana are very, very close friends and this has brought them even closer," a mutual friend of the couple told People, which first reported the news.

The anonymous source also told the magazine, "Although they aren't in a relationship, their friendship is extremely strong and they are both really excited about the baby."

This will be the first child for any of the One Direction guys, who recently kicked off the U.S. leg of their On The Road Again tour. 

Reached by Billboard, a rep for the band had no comment.
