Niall Horan has been snapped hanging out with Selena Gomez in London.

The One Direction heartthrob was seen posing for a pic with Justin Bieber's ex, who is thought to be in the capital for London Fashion Week.

The images of the pair have spread on Twitter, with a source suggesting to Hollywood Life that the popstar pair "made out for a bit".

The mole added: "Would she see [Niall] again? Yes. He’s being a gentleman and that is great for her.

"The last thing she needs is anything serious, but he’s cute and he likes her.”

Both Niall and Selena are yet to comment on the speculation, with the Irish heartthrob only recently splitting with model Barbara Palvin - who is also in town for London Fashion Week.
