Cue the waterworks! 'Glee' is getting ready to unveil its new Whitney Houston tribute episode, 'Dance With Somebody,' and by the looks of the preview for the show, it's going to a be a tear-jerker.

Rachel (Lea Michele) kicks off the preview with the signature lyric of Houston's 1985 hit 'How Will I Know,' which is woven throughout the clip. The episode focuses on New Directions dealing with their upcoming graduation and saying goodbye.

Tough guy Puck (Mark Salling) and sharp-tongued Santana (Naya Rivera) even let their guards down. "I'm only going to say this once," Puck begins. "I love you guys."

Next, Santana admits she's going to miss her favorite target. "Oh crap, I think I just realized I'm going to miss you," she says to Rachel. "Say something irritating so I can get the taste of this out of my head."

The clip ends with Mr. Schue (Matthew Morrison) asking Emma (Jayma Mays) to push the wedding up, and revealing that the kids in New Directions changed his life. Someone pass the tissues!

The 'Dance With Somebody' episode song list has yet to be released, but fans now know that at least the episode title track and 'How Will I Know' will be covered on April 24. Emotions are running high in the halls of William McKinley, and with the sounds of the late Whitney Houston shaping the show, we have no doubt that plenty of Gleek tears will be shed.
