Chris Brown Slammed by Pink, Joe Jonas Over Billboard Awards Lip-Syncing

Singers speak out in criticism of R&B star's mostly mimed performance from last night's ceremony—but what does Katy Perry have to do with it?

Everybody's a critic? When it comes to the stars who were treated—and we use that term as loosely as possible—to Chris Brown's Billboard Music Awards performance last night, well, yes.

And rather vocal critics, at that. Pink and Joe Jonas both slammed the R&B star's rendition of "Turn Up the Music," mincing no words when blasting the singer for miming his way through the tune.

"One day if i lipsync i hope i do it as well as him…" Pink, who seemed to more or less be livetweeting her way through the evening, began.

After getting a bit of backlash from Brown's fans, she tweeted again, "Oh my lord, its so easy…its so damn easy. Keep it coming people, this is some good reading…"

Her husband, Carey Hart, also got in on the Brown-bashing act, tweeting out his own professional opinion of the BMX-enhanced performance. Needless to say, it wasn't exactly a glowing review.

"Im pretty sure I saw my wife did that same performance, but she was 3 months pregnant and actually sang the song," he wrote, before addressing a fellow biker. "If any of your guys are riding on Chris Brown performance, please fire them."

Even Joe Jonas got in on the critical act, asking, "What happened to people singing live???"

As for Pink and Hart, however, while it seemed clear enough that they were referencing Brown's performance last night, they somehow raised the hackles of another fandom, that of Katy Perry. Her Katycats wrongfully believed that the criticism was directed towards their idol's performance, and both quickly cleared up any confusion.

"I love twitter!" Hart wrote. "To clarify I was talkin trash bout CB performance, 2 years ago my wife had the same set and actually sang 'Raise ur Glass.'"

"For the record; I luv me some Katy, so y'all can jump off that run away train, k?" Pink added. "I stand behind, always have and always will, LIVE SINGING."

For his part, Brown has maintained an uncharacteristic silence on the matter. Though, considering his lip-synced performance, maybe we shouldn't be so surprised that he's keeping his mouth shut.
