New video of Michael Clifford kissing Crystal Leigh likely confirms their long-rumored romance. So are any of the 5SOS members still single?

Clifford posted a cute video Monday night of Leigh kissing him as fireworks went off in the background. He included the cute caption, "I know I'm late, but happy new year everyone. especially to my love @crystalleigh for making 2016 infinitely better than I thought it would be. here's to much greener pastures in 2017, and much less awkward hand motions. (you know I'm bad at this)."

And even before Clifford posted the kissing video, there had been speculation that he and Leigh were an item. The duo recently vacationed together in Cancun and partied at Dirty Laundry.
