Jenny gave a surprise appearance during Pitbull's set at the Hollywood Bowl last night and did Live It Up. Killed it as usual, but I'm ready for single #2.

that was sooooooo fun!! this has to be one of her best performance routines shes had in years. its all so perfect.

please let's just forget this happened

A performance again? Ugh I love her, that's a real artist who believes in her own work! Go jen
