Britney Spears And Hayley Williams React To Last Night's 'Glee' In Today's Tweet Dreams

Last night's Britney Spears episode of "Glee" became an instant classic amongst fans, but there was one person who may have enjoyed it a little more than anyone else. Ms. Spears herself (who appeared in a few dream sequences) gleeked out on her Twitter after watching the "Britney/Brittany" ep. She had nothing but love for the other Brit, played by Heather Morris, posting, "Awww Heather Morris is sooo cute! Brittany S Pearce. Ha! She was so fun to work with and was really sweet in person." Britney (pictured here with Heather and "Glee" creator Ryan Murphy) also gave props to Lea Michele, Jane Lynch, Kevin McHale, Naya Rivera, Chris Colfer, and fellow guest star John Stamos before giving her final review of the show, "I loved it! Thank you guys SO much for making this happen."

But, Brit wasn't the only one with ties to last night's episode. Paramore lead singer Hayley Williams was blown away by Lea's teary take on her tune "The Only Exception." Hayley tweeted, "Holy exception!!! Dear everyone on Glee - you rocked the our song! @msleamichele your voice was sick!! I love your version more haha!" Hayley later informed followers, "Glee's version of "The Only Exception" is #4 on iTunes!! Dayuuuum! Thank you guys for being just as stoked as we are :)"
