The boyband star Louis Tomlinson is said to become a father with Los-Angeles based stylist Briana Jungwirth.

"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 told People.

Tomlinson and Jungwirth, who are both 23, were introduced through friends earlier this year after the One Direction star split up with girlfriend Eleanor Calder.

The stylist and the hearthrob were spotted at DBA nightclub in Hollywood together back in May.

The pop star has said he will be at Jungwirth's side and is ready to be a "hands-on" dad, and has reportedly been at every ultrasound so far. The baby's due date is said to be early next year.

There are reports that Tomlinson is looking at properties in Los Angeles near the stylist.

The friend said: "Louis and Briana care about each other very much and have spent a lot of time together privately over the last few months.

"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. It's early days and Briana and the baby's health are the most important things right now."

Adds the pal, "Briana is a really lovely girl; she's absolutely not interested in Louis' fame. She's very private and most of the time they spend together is out of the public eye, just hanging out with their friends."

Aside from breaking millions of young girls' hearts, it's said that Jungwirth had never even been to a One Direction concert until recently.

Little is known about the stylist so far, except that she shuns publicity, with no social media accounts, even though there are several fake accounts.
