Louis Tomlinson and Briana Jungwirth welcomed their first child, a son, on Thursday, Jan. 21 in Los Angeles, a source close to Jungwirth confirms to PEOPLE exclusively.

Tomlinson and Jungwirth met and briefly dated in last May following his split from longterm girlfriend Eleanor Calder that March.

Tomlinson has since been linked to reported girlfriend Danielle Campbell.

Tomlinson was spotted with The Originals actress in Chicago days before Christmas, followed by a night out in London just before New Year’s.

Early Friday morning, Tomlinson’s former stepfather, Mark Tomlinson, sparked speculation that the new addition had arrived with a Tweet: “Is that the patter of tiny feet?” he wrote.

A rep for Tomlinson could not be reached for comment.
