"I can't even breathe right now. Not Whitney. I'm in tears right now ;(" Riley tweeted upon hearing the news of Whitney's untimely passing on Feb. 11. "I had to pull over off the road. RIP Whitney Houston. I'm glad now that I got to meet you and thank you for your beautiful music," she added.
In addition to the prophetic Whitney tribute, the 'Glee' cast will cover seven other love songs as McKinley High hosts a Valentine's dance. Quinn, Mercedes and Sam take on Gym Class Heroes' 'Stereo Hearts' with new transfer student Joe Hart, played by 'The Glee Project's second winner, Samuel Larsen, in his first guest appearance.
Brittany and Santana run into some prejudices as they step out in public as a couple, and we are introduced to Rachel's gay dads Hiram and Leroy, played by Jeff Goldblum and Brian Stokes Mitchell! Will and Emma have a big fight, while Artie and Rory both try to win the heart of Sugar. Artie kills it on Mario's 'Let Me Love You' -- our vote's for him! Love birds Tina and Mike duet on Nat King Cole's 'L-O-V-E.'
And there's more! The cast takes on Cole Porter's 'You're the Top' from the musical 'Anything Goes,' 'Love Shack' by the B-52's, Michael Bublé's 'Home,' and a mash-up of Madonna's 'Cherish' with the Association's 'Cherish.'
