The One Direction family is going to get bigger!

In Touch can exclusively reveal Louis Tomlinson, 23, is expecting his first child with a woman named Briana Jungwirth, also 23 — and the current situation is being controlled by none other than Simon Cowell.

"Simon wants her to move to Cedars-Sinai Medical Center for treatment and birth, but she is refusing,” a source tells In Touch.

"While Briana and Louis still chat, Simon is controlling every move for this family.”

In fact, the source says the 55-year-old X Factor creator (who became a first-time dad in February 2014) is planning on moving Briana and her family to “The Oaks,” an exclusive neighborhood in Calabasas, “even though his preference was for her to be in a gated house in Beverly Hills close to Cedars-Sinai.”

So how does the crooner feel about the news? He’s particularly excited — because it puts a certain rumor to rest.

"Louis is not denying that he's the father and in fact is gung ho about the pregnancy,” the insider continues. "Close friends think that Louis believes this will put the gay rumors to rest.”

According to the source, Briana — who met Louis at a Snoop Dogg event in LA back in February following his split from longtime girlfriend Eleanor Calder — is about three months along.

“She got pregnant in late April 2015. She’s three months pregnant. The party girl has been hiding out and acting a bit neurotic about the whole thing,” the insider shares. “They’ve only hooked up 3-4 times, but of course that’s all it took to make him a daddy!”

Briana, who’s unemployed, still lives with her parents in Calabasas. Her mother, Tammy, is said to be ecstatic over the news. “She is delighted her daughter is pregnant and has been bragging to friends, family and really anyone who will listen about ‘Her One Direction baby.’”

But it appears drama could certainly unfold sooner than later, considering she’s American and Louis is British.

“The baby was conceived in LA, but she could face challenges for custody and financial support due to Louis being a British citizen,” says the insider, adding, "No paperwork has been filed as of yet, but Briana is preparing to retain a family lawyer to handle the child support, citizenship issues and privacy.”
