1D member to become a daddy!

New York - Louis Tomlinson is set to become a father, reports said on Tuesday, in the latest jolt for the boy band once known for its squeaky-clean image.

The 23-year-old, who would be the first dad in One Direction, is expecting a child with Los Angeles stylist Briana Jungwirth, according to British tabloid The Sun and People magazine.

The Sun - which ran the headline "One Conception" - said that Tomlinson went on dates with Jungwirth in May after breaking up with girlfriend of four years Eleanor Calder.

People magazine said that Tomlinson - whose British band has vowed not to split up after a recent feud - was looking forward to becoming a dad.

"They are both really happy and although they aren't in a relationship, their friendship is extremely strong and they are both really excited about the baby," an anonymous friend was quoted as saying.

A representative for the band did not immediately comment while Tomlinson last posted a video link on Twitter to raise support for a children's charity.

I want to live in a world where every sick child can see a doctor. https://t.co/f0rVZyrgaJ #action1D

One Direction stormed onto the scene in 2010 when the young men appeared on the British talent show The X Factor.
