Love is in the air at McKinley High! In honour of Valentine's Day, our favourite Gleeks have been challenged to find and perform the world's greatest love songs.
The episode also marks the arrival of Samuel Larsen, the other Glee Project winner that was awarded a stint on the show, and ... *drumroll* ... Rachel's two dads!
In an act of pure coincidence, Glee had also planned a cover of Whitney Houston's iconic song "I Will Always Love You" performed by Amber Riley.
Now the show's producers have revealed that they will dedicate the entire episode to Whitney such a beautiful tribute to an amazing woman!
