Ariana Grande has hinted that she has split from her boyfriend Nathan Sykes.

The US star and The Wanted man have seemingly been inseparable since revealing their relationship earlier this year, but Grande suggested that something may have gone awry.

Whilst appearing on 93.3 FLZ recently, the singer was asked how her relationship with Sykes is going.

Grande replied: "You're a little behind. We're really good friends."

The Wanted star meanwhile brushed off any possible split talk on Twitter today (December 20), saying:

"Ooooo I know what to say! Don't believe anything until you hear it from me or one of the boys. Everyyyoneee calmmmmm doooowwwwnnnnn."

When one fan asked if everything was okay, Sykes replied: "Everything is wonderful. Glad to be back on twitter! xx."
