Briana Jungwirth's big day has arrived! The fashion stylist finally gave birth to her baby with One Direction star, Louis Tomlinson.

According to People, 23-year-old Jungwirth gave birth to Tomlinson's son on Jan. 21, Thursday, in Los Angeles. The news came from a close friend of Jungwirth who reported to the news outlet exclusively.

The "Perfect" singer also confirmed the news on Twitter early morning of Jan. 23. "I'm pleased to say my baby son was born yesterday :) He is healthy and pretty amazing :) I'm very happy!!" he wrote.

A mutual friend of both Jungwirth and Tomlinson also told People that the One Direction member is excited about becoming a parent and also thinks Jungwirth "will be an amazing mother."

Jungwirth and Tomlinson met in May 2015, shortly after the latter split with then-girlfriend Eleanor Calder. The "Drag Me Down" singer and the celebrity stylist were spotted several times on a date that month. In July 2015, it was confirmed that they were expecting their first child together.

Currently, Tomlinson is reportedly dating "The Originals" actress, Danielle Campbell. They were captured in photos days before Christmas and was spotted again in London before New Year's Eve, according to reports.

Despite Tomlinson reportedly dating a different girl, he and Jungwirth have remained good friends. As for the stylist, she has maintained her private life ever since news broke out that she got pregnant by the celebrity.

Everyone wanted to get a piece of information about the mysterious Jungwirth, but she and her friends were quick enough to delete social media accounts to stay away from the public eye, Mirror reported.

One Direction is currently on a break as Tomlinson prepares for fatherhood. However, according to Us Weekly, the extended break means that the band is actually breaking up. The news outlet reported that Tomlinson, along with Liam Payne, Harry Styles, and Niall Horan, didn't renew their contracts.

It appears Tomlinson will have more time to be with his son now.
