Whitney Houston is posthumously getting the Glee treatment.
On Tuesday's all-new episode, the New Directions gang -- including Rachel (Lea Michele) and Mercedes (Amber Riley) -- will pay tribute to the late pop diva with an hour-long episode peppered with her greatest hits.
"Whitney's music meant so very much to me. I was very very choked up when I heard about her passing," the actress told E! shortly after Houston's untimely death. "I've grown up listening to her voice ringing throughout our household. I'm so speechless. I can't believe that she passed."
