Louis Tomlinson is set to become a first-time father any day now and it looks as if the mother of the One Direction singer's unborn child is bumping along nicely. Briana Jungwirth has send Directioners into a frenzy after allegedly posting a snap of her burgeoning belly.

The LA-based stylist shied away from the limelight after news broke that she was expecting the 24-year-old singer's baby back in July 2015. Although it was widely-reported that she had disappeared from social media, some eagle-eyed fans have been led to believe that she has returned to Instagram and is posting regular updates.

The account under the handle @brianaashleyjungwirth was launched in December and already boasts over 41,000 followers. When the account holder shared a picture of an apparently heavily pregnant Jungwirth captioned: "Beyond grateful for such a beautiful day" many of those subscribers couldn't hold back their excitement. The snap has received more than 13,000 likes.

"You look amazing briana," one follower said of the image of 'Briana' wearing a short black dress and gazing down at her growing baby bump.

Another added: "Your baby will be beautiful like you and louis."

Although Tomlinson has remained tight-lipped about stepping into fatherhood, it was recently reported that the pair, who are not together, are having a little girl. The bump picture comes days after the former X Factor contestant was romantically-linked to US actress Danielle Campbell. The pair first sent tongues wagging when they were spotted hugging while getting ice cream together in Chicago on 21 December.

"Danielle and Louis are really into one another. She's flown [to the UK] just a week after he was with her in her home town," a source told The Sun. "She's been enjoying herself, sightseeing with pals in the day, but it's clear they'll see each other away from prying eyes."
