The One Direction star, 23, is expecting his first child with former fling Briana Jungwirth later this year - and is said to be serious about committing to his role as a father.
Now, it's been reported that Louis has 'real feelings for Briana' and that the pair may well stick together.
Louis' relationship with US stylist Briana is thought to have lasted a matter of weeks.
And fans were shocked when news of her pregnancy broke earlier this month.
According to The Sun, the pair have recently met up several times and may well make a go of things.
A source told the newspaper: "Louis is sacrificing all his spare time to see her.
"There are very real feelings there. It's not just about the baby."
Briana, 23, is thought to be about three months pregnant, so should be due at the end of this year.
Louis has yet to comment on the news he's to be a dad.
However, he did thank his fans for their support, tweeting: "You have been by far the most incredible fanbase and nothing you do goes unnoticed. We are so lucky to have you guys! Thanks so much :)."
He split with long-term girlfriend Eleanor Calder earlier this year after four years together.
