Today on Twitter, Lady Gaga unleashed some pretty big news. The cross-dressing superstar (no, not Jo Calderone) tweeted that she is planning to release five new 'You and I' videos in just a few hours. She didn't say much, only that they're 'fashion films' -- so perhaps Mr. Calderone will get some more screen time this afternoon. While the rest of today's tweetings don't hold a candle to the goodness of Gaga, 'Glee' star Lea Michele did share that she's watching her friends Heather Morris and Amber Riley rock it on set. Also, Justin Bieber used his tweets to sing Sean Kingston's praises, and Jennette McCurdy discovered some children who aren't very in touch with classic films.
