We all know that Nick Jonas doesn't like to 吻乐队（Kiss） and tell, but this time we may have caught him red handed. It seems that Nick has been getting really close to his Les Miserables co star, 20-year-old British actress Samantha Barks.

While at the Les Miserables 25th Anniversary afterparty, the two were spotted dancing and holding each other’s hands throughout the night. When asked 由 People Magazine about his personal life, Nick said, “I keep that stuff to myself." However, when Samantha was asked about Nick she could only giggle and reply back, “Nick is such a wonderful person."

Not only were they spotted 表演 friendly at the Les Mis afterparty, some very lucky schoolgirls spotted the costars at the 伦敦 Zoo today. While on a fieldtrip, some 伦敦 teens claim they saw Nick and Samantha holding hands while checking out the monkey exhibit. A Twitpic definitely confirms that Nick spent the 日 at the zoo, but unfortunatley there's no 照片 evidence to back up the alleged handholding.

In Les Miserables, Samantha plays Eponine, who suffers from unrequited 爱情 for Nick's character Marius. Has Samantha fallen for Nick like her onstage character?
