Ariana Grande and Nathan Sykes record love song duet?
Ariana Grande has apparently duetted with Nathan Sykes on his ballad 'Over And Over Again'.
The former lovers - who dated briefly before parting ways in December 2013 - have hinted they've teamed up after Ariana, 22, teased fans by sharing lyrics to Nathan's single, which he admitted is about their relationship, on her Twitter.
Taking to the micro-blogging site, she wrote: "from the heat of night to the break of day I'll keep you safe & hold you forever #OverAndOverAgain (sic)"
And the former The Wanted star re-tweeted his former beau's tweet.
A source has revealed the pair have been in touch recently while they are working on both of their forthcoming albums.
An insider revealed: "Nathan and Ariana always cared for each other and the main reason they broke up was that their careers made it impossible to see one another.
"They lost touch for a while but they've recently been chatting again while they each record new albums."
The singers first met when they collaborated on 'Almost Is Never Enough', which was added to the 'Love Me Harder' hitmaker's 2013 LP 'Yours Truly'.
The source added to The Sun Online: "Nathan sang on Ariana's first album so she felt it was only fair to repay the favour - even though they aren't together any more."
