It hasn't been that long since she split from her musician boyfriend Mac Miller, but it seems that Ariana Grande is already enjoying a new romance.

The pop star is reportedly 'quietly dating' Pete Davidson from Saturday Night Live, as People magazine report that the two 24-year-olds just started a 'very casual' relationship after meeting and hanging out on the set of SNL.

Grande appeared on the show in March 2016 - when she was the celebrity host and performer - and they have reportedly kept in touch.

With Miller out of the picture, it apparently didn't take the young comedian long to swoop right in there - and he was even backstage at the Billboard Music Awards to support his new lady on Sunday night. There are also rumours that the pair may have matching tattoos.

The news has both surprised and amused people:
