Nick Jonas once wore a purity ring and sang with The Jonas Brothers. Now he sings by himself and (most probably) has sex. Good for him.
Nick Jonas was one third of The Jonas Brothers with his older brother Joe and the other one. They were notable for wearing purity rings while all having girlfriends, which at the time was not suspicious at all. Sadly, they split in 2010. After that Nick 2.0 arrived, firstly as the sinister-sounding 'Nick Jonas and the Administration', and now just as 'Nick Jonas'. He's since released two solo albums and hasn't skipped leg day at the gym for almost 3 years.
Fun fact: No one truly knows what happened to Nick's purity ring in the end. If you know, please do get in touch.
