London, Sep 7 (IANS) Actress Ariana Grande and Big Sean's relationship is reportedly getting serious.

The duo, who recently started dating, is said to be smitten with one another, partly thanks to the hip hop artist's romantic gestures. Their friends think the they're the perfect couple.

"Sean asked Ariana out in a romantic way and they went to the movies. Now it's gotten serious very fast. They are much happier than in their previous relationships. He's a good guy and she's a sweet girl. They really gel,” femalefirst.co.uk quoted a source as saying.

Grande recently admitted she was "happy" with her latest relationship.

Asked about her love life on the “Today” show last week, she said: "Oh, my goodness! You are putting me on the spot. I'm happy."

The couple appeared to confirm their relationship status last month when they were caught on a behind-the-scenes camera at the MTV Video Music Awards (VMAs) holding hands as they walked down a corridor.
