In GLEE’s special episode dedicated to Britney Spears (s02ep02) on Tuesday (September 28), McKinley High’s Glee club singers had incredible wild fantasies about the Princess Of Pop while under anesthesia at the dentist (played by John Stamos)- watch video below.

The cast did six of Britney’s biggest hits all while resurrecting her most iconic costumes, including the “Oops … I Did It Again” red-leather bodysuit; the bejeweled (and nearly naked) “Toxic” look; the “I’m a Slave 4 U” green bikini, complete with snake; Madonna and Brit’s “Me Against the Music” menswear-inspired suits; the “(Baby) One More Time” schoolgirl uniform; and, finally, a stirring rendition of “Stronger.”

Britney, who made special “hallucinogenic” appearances on the show, crashed Brittany’s (Heather Morris) fantasy of “Me Against The Music” featuring Santana (Nadya Rivera). Brittany to Britney: “You’re really hot!”

In another scene, Britney is dressed like a hot cheerleader while talking about pizza toppings in Artie’s (Kevin McHale) dream. The “Britney/Brittany” episode was absolutely incredible. Best GLEE episode ever! And there’s more: Britney’s episode is rumored to have a sequel sometime in the next season of FOX’s hit TV show.

Britney Spears live “tweeted” GLEE’s Episode:

Britney said, “Awww Heather Morris is sooo cute! Brittany S Pearce. Ha! She was so fun to work with and was really sweet in person. John Stamos is still hot! He looks the same as he did on Full House. I like Kurt’s bow tie. Bow ties are sexy… I hate anesthesia!”

“Slave: Oh…My…God…! I know how hard it is to dance with that snake! Nice job…. The Me Against The Music set looks just like the original. Santana does a great Madonna impression. Watching Baby brings back so many memories! Feels like yesterday….”

“Jane Lynch scares me. Jane Lynch is hilarious and scary all rolled into one. I love this version of Stronger. Artie did a great job. The GLEE version of Toxic is amazing! I loved it! Thank you guys SO much for making this happen!”
