The cast will perform "How Will I Know" on the episode, set to air Tuesday
Glee stars Lea Michele, Amber Riley, Naya Rivera and Chris Colfer have recorded a new tribute to Whitney Houston.
The stars recorded an a capella version of Whitney Houston's "How Will I Know" for an upcoming episode devoted to the late singer, which will air in the U.S. on Tuesday, April 23.
Amber Riley (who plays Mercedes on the show) previously performed a moving rendition of Houston's hit, "I Will Always Love You," which coincidentally aired the week following Houston's tragic death. The video of her performance on YouTube has since racked up more than 8 million views.
