Chris Brown's performance during the BET Awards on Sunday was supposed to be an emotional experience for everyone involved. It was both a tribute to Michael Jackson and Brown's return to performing after being dogged by ugly headlines about his relationship with Rihanna. So he capped it all off by shedding a few tears. But according to Us Weekly, they were the tears of a clown. Brown used special tear-inducing eye drops to break down during his rendition of "Man in the Mirror." A source backstage claims he administered them just before going on and then, "He rubbed it in and he started crying," the source said. Brown's camp, of course, categorically denies the allegation, saying the story is "completely untrue."
