-_- Is "Selena Gomez" in Niall Horan's house in this hot Instagram selfie! TBT snap sparks fan excitement ???

After Selena Gomez met up with One Direction hunk Niall Horan in London last month, we got very excited about a possible romance on the cards.

And it seems we weren't completely off the mark - because fans are claiming this hot selfie of the Disney star and her friend Samantha Droke was taken at his actual house.

Samantha posted the TBT snap with the caption: "That time in London Town so much love for this one #lilsis #TBT #missu."

But, for once, fans were drawn away from the pairs' beautiful faces and to the background, which apparently looks like Niall's house.

One Instagram user wrote: "That is Niall's house!" And another added: "ISNT THIS NIALLS HOUSE."

Ooer.

The brunette lovelies spent a lot of time together on Selena's action-packed trip to Blighty last month - before the star was spotted on a night out with Niall.

Excited fans posed for pictures with the pair - and they have been shared by most of Twitter - who looked to be enjoying their time together - despite Niall's former flame also being out and about in the city.           

The star was certainly full of the joys of spring this week after posting a video to Instagram of her singing along to Tequila Sunrise in her car.

What CAN all this mean?
