Short answer: we don't know!
Twitter is awash with speculation that Briana Jungwirth has given birth to a baby boy, apparently because a woman claiming to be her grandmother confirmed the news on social media.
There's been absolutely zero statement from Louis or his management, though we suppose that's no surprise given that since the baby news surfaced back in July, neither have really made any public comment.
Louis confirmed the pregnancy on a US TV show, saying he was "buzzing" but apart from that it's been silence.
A lack of official word on the baby's safe arrival hasn't stopped thousands of One Direction fans taking to Twitter to share their congratulations, skepticism, jokes and everything in between.
I'm still unclear as to whether this baby is still inside Briana or not hopefully Louis isn't as confused as me #WelcomeBabyTomlinson— mallika (@aimlessphan) January 22, 2016
"We have no idea if Louis's baby is here or not, but let's make sure it's trending anyway!" Okay, then... pic.twitter.com/qxchaPKhbv— elodie. (@czzerny_) January 22, 2016

Louis and Briana's baby news came as a shock to many fans who hadn't realised they'd been dating. Many didn't know of Briana or her background until the baby news sent everyone digging for info.
It is believed they shared a few dates in May last year after Louis split from long-time girlfriend Eleanor Calder. He's now thought to be dating US actress Danielle Campbell, but is allegedly planning to relocate to LA to be close to his child.
