CHEAT SHEET
TOP 10 RIGHT NOW
Every queen of pop—from Madge to Britney—reaches a moment when they realize they've been pushed to the edge, and just need a break. The latest queen, Lady Gaga, reached her moment Thursday, when she collapsed before a performance at Purdue University in Indiana. The singer canceled the show, along with her following performance Jan. 18 at the Mohegan Sun Arena, citing exhaustion. Known for her elaborate concerts, it comes as no surprise that the performer finally reached a breaking point, and she is profusely apologizing to fans via Twitter, posting "I hope you can forgive me. I love my little monsters more than anything, you are everything to me. I will make up the performance on Jan 26."
