Taylor Swift's Grammy performance has been criticized for not being lively enough, and rapper Wiz Khalifa was actually put to sleep during the segment. During an interview with Joan Rivers and the "Fashion Police" crew, Wiz revealed that he dozed off while Taylor sung "All Too Well." 

"I love Taylor, but I'm not even gonna lie, I fell asleep," he said. "Just a little bit . . . then I woke back up."

Wiz and Taylor have been friendly for years, with Amber Rose even speaking up during her husband's conversation, saying "We love Taylor." In May 2012 the two even posed for an Instagram photo together with the caption, "Me N Taylor Gang."
