The Wanted star Nathan Sykes and Amy Winehouse's goddaughter Dionne Bromfield have sparked speculation of a new pop romance after they were spotted getting close at Nicki Minaj's London concert on Monday night.

The 19-year-old boyband singer and longtime friend Bromfield were among the crowd at Minaj's show at the Hammersmith Apollo, and they weren't shy about showing their feelings for each other.

A source tells Britain's The Sun, "Nathan and Dionne have been out on a few dates but were keen to take it slowly. Things have clearly stepped up a gear now, though."

"They were very touchy-feely at the show and didn't care who saw them. They've known of each other for a long time, they went to the same school and Dionne supported the group on a few of their festival gigs last year."
