Nick Jonas has reportedly been on a date with former X Factor contestant Lucie Jones.

The singer-songwriter is currently playing Marius in the West End production of Les Miserables, in which Jones is starring as Cosette.

According to The Sun, Jonas has also been on a date with third-placed I’d-Do-Anything-star Samantha Barks, who is playing Eponine in the London show.

A source told the newspaper: “Nick is getting a reputation as a heart-breaker. He’s been out on dates with both Samantha and Lucie and they both seem quite smitten.

“Nick’s just having fun – but he’s causing some tension between the girls. There’s been a lot of jokes backstage because art is imitating life. In the musical Eponine fancies Marius. But he ends up with Cosette.”
