JoJo invites fans on her bus as she prepares for the first stop of her nationwide tour with Joe Jonas and Jay Sean in Boston. The hometown gal reminisces about her first paid gig, playing a fairy in “A Midsummer Night’s Dream” at the Huntington Theatre, and beams with pride as she drives by the famed Fenway Park. The 20-year-old singer, whose new single “Disaster” cracked the top 50 on iTunes, is also seen performing at the kickoff and happily posing for pictures with fans after the show.
