Fresh off of his Grammy performances and the backlash from music fans and celebrities alike, singer Chris Brown is being accused of making light of his 2009 assault conviction.

According to a report from Us Weekly, the singer –who pleaded guilty to felony assault of his then-girlfriend Rihanna in 2009 – has reportedly been using the pick-up line, “I promise I won’t beat you.”

A woman tells the magazine that Brown approached her on Feb. 10 at the Lasio Professional Hair Care suite at the Grammy gift lounge to ask for her number.

“Can I get your number? I promise I won’t beat you,” the woman said he told her.

“He and his friends laughed, then one yelled, ‘That’s his new line!’” she said. “I wanted to throw up.”

Following the Grammys Sunday, Brown’s two performances and one win have received significant criticism on social networks.

Country singer Miranda Lambert wrote on her Twitter page, “He beat on a girl ... Not cool that we act like that didn't happen. He needs to listen to Gunpowder and lead and be put back in his place. Not at the Grammys.”

“Gunpowder and Lead” is one of Lambert’s songs that deals with domestic violence.

Other celebs including Jack Osbourne, “Modern Family” star Eric Stonestreet and Michelle Branch similarly expressed frustration for Brown’s appearance.

According to Us magazine, Rihanna and Chris Brown have been spending time together over the past year and may even be recording a single together.
