The upcoming episode will feature eight songs by the late Houston, according to E! Online, which first reported the news. It also won't be a straight-up tribute like past Madonna and Michael Jackson-themed episodes. Instead, the songs will represent the hard time Glee's graduating seniors are having with moving on.
Last month, Amber Riley performed Houston's hit "I Will Always Love You," which was planned prior to the singer's death.
Glee returns with new episodes Tuesday, April 10, at 8/7c on Fox.
