Ariana Grande thinks Big Sean is an "amazing" man.

Speaking in the upcoming issue of the Sunday Telegraph's Magazine, Ariana, who lost her grandfather in July, said of her new beau: "He is one of the most amazing men in the world, and that includes my grandfather and my brother.

"I think the world of him, and he's an amazing person. That's kind of all there is to it."

The pair sparked rumours they were dating after they were caught holding hands on a behind-the-scenes camera at the MTV Video Music Awards in August.

It seems their relationship is going from strength-to-strength and they even make sure they keep their romance alive when work commitments separate them.

A source said previously: "She's [Ariana is] having a great time [on tour] but she really misses him [Big Sean], it's hard because they're in love, so of course they don't want to be apart.

"They talk every night before she goes to bed, she doesn't even want to go out after dinner with everyone because she just wants to get back to her room and talk to him, she's got it bad."

News that Ariana and the hunk - whose real name is Sean Anderson - were dating came as a shock to fans as he'd only ended his five-month engagement to 'Glee' actress Naya Rivera in April this year.
