Ariana Grande and Nathan Sykes from the Wanted collaborated on 'Almost Is Never Enough,' and it looks like they're mixing business with pleasure. The pair, who shared a spellbinding duet, are dating now!

"It's very, very new," an insider told Us Weekly. That's probably true -- Grande only just broke up with longtime boyfriend Jai Brooks last week, and Sykes had been linked to Dionne Bromfield until April. The source says Grande and Sykes had met each other a few times, but didn't begin dating until recently.

Another source revealed something super cute: "Nate sends her flowers everyday."

We bet the only person happier about this pairing than Grande and Sykes themselves is their shared manager, Scooter Braun -- whom Grande also said pressured her into releasing that kiss photo with Justin Bieber. Imagine the awesome press these two will generate together!
