This is quite the surprise! For us AND Louis Tomlinson, it seems...

The One Direction singer is going to be a father, and though he hasn't officially confirmed the news, a source tells Us Weekly that the boy bander is expecting a baby with his stylist friend Briana Jungwirth.

The insider tells the mag:
    "Louis didn’t expect this, but he’s excited for it now. He’s become very close friends with Briana this year and now they are looking forward to being parents. He’s definitely going to be there and be a great dad for their baby."

Tomlinson, 23, and Jungwirth, also 23, met last March shortly after he broke up with his girlfriend of two years, Eleanor Calder.

Tomlinson plans on co-parting with Jungwirth, though the source points out that Tomlinson is still "very much single." Jungwirth and Tomlinson's parents met in Los Angeles earlier this month, so it seems like they will be very much involved in raising the child as well. "[Louis and Briana] aren’t together but are both happy about having a child," the insider says. "They aren’t a couple and the pregnancy is in the very new [stages]. They just found out.”

Uh, congrats?
