Today on Twitter, 'Glee' cast members Lea Michele, Darren Criss, Cory Monteith, Chris Colfer and Kevin McHale were all basking in their Glee glory as they filmed their 300th performance on the hit TV show. Chris Colfer joked that the cast would dress up as Spartans and heave spears at each other like the movie '300.' Or was he really kidding? Kevin McHale let us in on the secret that the cast will be performing a legend's music. Anyone got any guesses about that one? Speaking of 'Glee,' Kelly Clarkson was thanking Lea Michele for the kind words she tweeted about Ms. Clarkson's album yesterday. Miley Cyrus posted a picture of her adorable pup Floyd and 'The Voice' runner-up Dia Frampton announced that her debut album is finished! Finally, Sara Bareilles was getting in on the Christmas cheer, but we think she might be drinking in some holiday cheer. See what your favorite stars were chirping about today!
