It looks like love is in the air for 5 Seconds of Summer's Luke Hemmings and X Factor US winner Sierra Denton with a few rumours swirling that the pair are dating.

While the pair are yet to actually confirm things, they have been posting an increasing number of cosy pics of each other, which has got fans thinking that they are most likely a little more than friends.

The pair have been hanging out for a few months with increasing appearances on each other's social media accounts.

Then in Junethe pair were seen out and aboutholding hands, pretty much cementing the rumours that they might just be a thing.

And now they've gone Instagram-official, sharing some super cuddly photos together on their GRIDS. And if that isn't real deal love in the age of social media, we really don't know what is.

ICYMI, Sierra first burst onto the music scene after winning the third season of the US X Factor, alongside then-boyfriend Alex Kinsey. The duo separated and a year later broke up the band, letting Sierra now venture into solo territory.Her new single ‘Don’t Hurt’ is alllll about the six-year relationship she had with Alex, and it’s a major bop.

Fingers cross for a Sierra and 5SOS collab next time around, but in the mean time we could probs make do with a few more of of these feels-inducing snaps. Hbu?
