Maybe you've noticed, but after something of a musical hiatus, JoJo is back. You still remember her, right? Because it's only been 5 years since her last album (2006's The High Road). She'll drop her third LP, Jumping Trains, in October. But until then, she'll be posting twitpics of herself in skinny jeans so we have to pay attention to her. Because seriously, how can we not, when she looks like that.
