Nick Jonas' 'Les Miserables' Co-Star Denies Romance

'He's a great friend but nothing more,' Lucie Jones tweets.

Photos of Nick Jonas and his "Les Misérables" co-star Lucie Jones hanging out together in London in their off time had fans wondering if there was a workplace romance. Well, according to Jones, there's nothing of the sort happening between the pair.

"Hey everyone ... just wanted to clear up a rumour - there's nothing romantically happening between nick and I guys!" Jones, who plays Cosette in the West End production of the play and was on "The X Factor," tweeted. "He's a great friend but nothing more. Hope you're all well, love you guys!"

Jonas also tried to do some rumor control on his own Twitter page, clearing up speculation about his relationships with two of his co-stars. "The story about me dating both my costars Samantha Barks AND Lucie Jones is untrue," he wrote on July 1. "I love and respect the people I work with very much."

Jonas is currently playing Marius in the show. He starred in the Broadway version as Gavroche in 2003 before he found fame with the Jonas Brothers. "The amazing [theater producer] Cameron Mackintosh reached out to me last year about portraying the role of Marius in London at the West End. On my closing night in 2003 I told my parents that I would come back to be Marius one day," he said shortly after announcing he would be joining the show. "It is truly a dream come true."

Once he ends his run on the West End, he'll meet up with his brothers again for the Jonas Brothers' summer tour, which kicks off in August. Then, "Camp Rock 2" is set to premiere on Disney in September.
