LOL! CHRIS BROWN SLAMMED FOR PULLING A MILLI VANILLI!

Another awards show, another round of Chris Brown bashing.

The 23-year-old R&B singer took to the stage at Sunday night’s Billboard Music Awards, but it didn't take long for fans and celebrities alike to call him out for his pronounced lip synching.

Pink led the pack on Twitter.

“One day if I lipsync i hope i do it as well as him...” she wrote after witnessing Brown mouth his way through his hit “Turn Up the Music.”

Later, she shared a few more of her thoughts.

“Oh my lord, its so easy...its so damn easy,” she commented. “Keep it coming people, this is some good reading...”

The act featured Brown and several bikers riding glow-in-the-dark bikes on a giant ramp onstage.

Pink’s husband, motorcycle racer Carey Hart, had a few words of his own to add to the conversation.

“Im pretty sure I saw my wife did that same performance, but she was 3 months pregnant and actually sang the song,” he tweeted, referencing Pink’s 2010 performance of “Raise Your Glass” at the American Music Awards.

Shortly afterward, he was pounced upon by Katy Perry fans who mistakenly thought he was referencing their singing idol.

He later clarified that he was bashing on Brown’s performance, not the “California Gurls” singer, but not before managing to get a slight jab in at Perry's KatyCats.

“Looks like someone else’s fans got a bit wound up!” he wrote. “Funny, that performance looked real familiar too.” YOUTUBE SOURCE
