An upcoming episode of the US music-themed series \"Glee\" will feature eight songs by late recording star Whitney Houston, E! News said. Cast member Amber Riley performed \"I Will Always Love You\" and producers added a dedication card at the end of an episode last month, shortly after Houston died at age 48. A show source told E! the new episode was planned after Houston\'s death and will \"not be a typical tribute.\" \"It\'s using Whitney\'s music as a way to say goodbye,\" the source said. \"A way to respectfully say thank you for her music.\" \"Glee\" co-star Lea Michele mentioned the episode via Twitter Friday. \"Starting a new episode today. A very special tribute to one of the world\'s most amazing singers. Very excited about this one,\" Michele said. An air date has not yet been set for the episode.
