Does Niall Horan have a secret girlfriend?

It’s time we shed some light on the world’s worst kept secret.

Does Niall Horan have a secret girlfriend?

You may need to take a seat for this bit of 1D news girls, as it seems like Niall Horan may be (unofficially) off the market.

Niall was recently spotted leaving an event with rumoured girlfriend Melissa Anne Whitelaw, and now reports are swirling that they're getting even more loved up!

Even though we hadn't spotted them together since they were hanging out in Australia, ol' Niall is said to be one smitten kitten.

“Melissa met the rest of the band on tour, when she first grew close to Niall, but after flying over to spend time with him they now see her as his girlfriend," a source told The Mirror.

"She attended the Great Gatsby-themed charity ball – arranged by Liam’s girlfriend Sophia [Smith] – with Niall, as his plus-one, though they tried to be discreet. She also went along to [the after party at] Mahiki with him, where they seemed to be really serious about one another by the way he was introducing her to people. She was a real hit with all his friends.”

Dang nabbit!

Admittedly, there's been no OFFICIAL word from Niall about his budding romance, so for now, let's pretend he's still a single pringle. OK? OK.
