Ariana Grande, The Wanted's Nathan Are Dating! -- But 'Terrified'

Couple confirms their relationship via Twitter after photos surfaced of them holding hands in Disneyland.

Adorable new couple alert! Ariana Grande and the Wanted's Nathan Sykes confirmed that they're officially an item.

Rumors have been swirling for weeks that the "Almost Is Never Enough" collaborators were dating, with Grande recently telling "Access Hollywood" that even though Sykes is "amazing," they weren't seeing each other.

Yet there was no denying the romance after photographs surfaced of the pair in Disneyland holding hands, posing for pictures and hugging, as Grande sported Mickey Mouse ears.

On Tuesday (September 24), the two stars took to Twitter, confirming the not-so-secret news with Sykes revealing that he's "so happy" before adding the hashtags #butweareterrified #pleasedontkillme.

Shortly after, Grande added that she and Sykes hesitated making the relationship public since people can be "a bit insensitive," but thanked fans for looking out for their happiness.

So far, fans seem to be onboard for the new pairing, with Arianators and TWFanmily showing their support.

"@NathanTheWanted I mean it was kind of obvious Nathan haha but I'm happy for you and y'all are so cute together❤," @tattoomymusic wrote.

Another fan @smileysophie4ev tweeted, "@ArianaGrande Just so glad that you're happy, when you're happy I'm happy, I love you two together, just so happy, love u so much ♡"

Grande and Sykes teamed up to record the "Mortal Instruments" soundtrack song "Almost Is Never Enough," which is also featured on Grande's #1 debut album, Yours Truly.

"Honestly, I couldn't ask to work with a more talented vocalist than Ariana," Sykes told MTV News of working with Grande. "I have so much respect for what she's just about to do, and I think it's a very exciting time for both myself and Ariana for slightly different reasons. I'm just excited I got my voice back [after vocal surgery]. She's about to go on this quite amazing journey."
