Chris Brown's performance at the Billboard Music Awards left some of his fellow singers less than impressed, most notably Pink.The singer and her husband Carey Hart called Brown out for lip-synching his current hit "Turn Up the Music" Sunday night during the award show.

Pink tweeted to her fans, "one day if i lipsync, i hope i do it as well as him...." Hart chimed in with, "Im pretty sure i saw my wife did that same performance, but she was 3 months pregnant and actually sang the song."

And model Chrissy Teigen weighed in with, "Why sing when you can dance?"

This is just a few months after celebrities and others voiced their objections to Brown's performance at the Grammy Awards, three years after assaulting then-girlfriend Rihanna.
