Ariana Grande's ex-boyfriend Nathan Sykes is relieved he wasn't name-checked on the singer's latest single 'thank u, next' about former flames.

The 25-year-old pop star name-checked ex-fiance Pete Davidson, the late Mac Miller, Big Sean and backing dancer Ricky Alvarez on 'thank u, next', and the British singer - who had a brief romance with the "Dangerous Woman" hitmaker in 2013 - has admitted he's delighted that he was left out.

Asked if he's heard the track, the 25-year-old star told TMZ: "I haven't yet. I've heard it's good though. 

"That's good then - that's nice. I hear it's amazing, so fantastic. 

"If people are releasing good music and they are happy with the music they are releasing, then I think that is great."

When quizzed on what he thinks Ariana learnt from their time together, he replied: "That's not a question for me. I don't tell anyone what they can learn from me."

Admitting that he has grown up a lot since then, he added: "It was a long time ago. I suppose you just grow as a person, don't you? We were very, very young."

And when asked if he'd consider dating Ariana again now she is single, he insisted: "No. As I said, it's a long time ago."
