The singer is expecting a baby with stylist Briana Jungwirth, according to People.
“Louis is happy and very excited about becoming a dad and he thinks Briana will be an amazing mother," a mutual friend told the magazine. "It was a surprise at first, but he and Briana are very, very close friends and this has brought them even closer."
People reported that Tomlinson and Jungwirth, both 23, met through mutual friends earlier this year though they are not currently in a romantic relationship. However, the singer has been flying from Europe to L.A. to be present for ultrasounds and has also been eyeing properties on the west coast. His parents have also met hers.
They “really hit it off when they met,” the friend said. "They are all excited and totally supportive."
It's been a year of change for the members of One Direction. In March, Zayn Malik left the band and in April, Tomlinson, who has said that the band will not break up, launched his own record label.
"This is something I’ve wanted to do for some time, and to be given the opportunity to potentially give new artists a platform is an incredible feeling," he told the Sun newspaper at the time.
