The Internet is buzzing over the relationship between Joe Jonas and Ashley Greene. Now, brother Nick is doing his sibling a favor and diverting attention away to his own love life: at the afterparty for the 25th anniversary production of Les Miserables in London last night, onlookers say Nick looked awfully cozy with co-star Samantha Barks. Samantha Barks is the fortunate meat in this Jonas brothers sandwich. The pair walked around holding hands and mingling with guests, which included Joe, Ashley, Kevin Jonas and his wife, Danielle. "Nick is such a wonderful person. We definitely keep in contact," Samantha said, while Nick remained mum and simply replied to a question about the 20-year old actress with: "I keep that stuff to myself."
