The rumours are back once again. Are Nick Jonas and Samantha Barks dating?

The pair met on the set of Les Miserables, and after both attending the afterparty for the 25th anniversary production of the show the couple have been romantically linked once more. An onlooker claims that the pair were looking cosy together according to thehollywoodgossip.com.

The site also reported that the pair walked around holding hands and mingling with guests, which included brother Joe Jonas, Ashley Greene, Kevin Jonas and his wife, Danielle.

“Nick is such a wonderful person. We definitely keep in contact,” Samantha said, while Nick reportedly remained almost silent and simply replied: “I keep that stuff to myself.”
