Exclusive Smash Preview: Karen and Jimmy Kiss Again -- But There's a Twist!

Karen and Jimmy agreed to keep things strictly professional on the latest episode of Smash, so how come they’re back and locking lips in this exclusive preview video from next Tuesday’s episode, “The Fringe” (10/9c on NBC)? And why the heck is Derek staring moodily at the Broadway babies while they go at it?

As you might’ve guessed, the big smooch happens onstage — while the twosome performs the ballad “Heart-Shaped Wreckage” from Jimmy’s musical The Hit List during its Fringe Festival debut. And Derek — as he sometimes likes to do — upgrades the minimalist staging and sets in his director’s mind. (Not only that, he reimagines Karen with darker, wavier hair — a decision I enthusiastically support!)
