Ariana Grande and Big Sean are "loved-up".

The couple confirmed they were an item in October and in a candid interview, the 21-year-old songstress has gushed about her rapper boyfriend, describing him as "a sweetheart".

She shared: "I like boys with a bad boy kind of style, but Sean's the best boy I've ever met. He's a sweetheart."

She told Now magazine: "I'm not that open... I'm still a little shy about it. But I am very happy and very loved-up."

Ariana has previously dated Nathan Sykes from The Wanted and internet comedian Jai Brooks.

Meanwhile, Big Sean was formerly engaged to 'Glee' actress Naya Rivera.

The couple have been coy about the status of their relationship for the most part, but in an interview with Ryan Seacrest in September, the 26-year-old hip-hop star couldn't hide his admiration of Ariana.

He said: "That Ariana is very, very special. She's very special to me.

"Everything she has going on is good with her, everything I have going on is good with me, everything between me and her is good, and I'm just going to leave it at that."
