‘I’m on the attack now’: Chris Brown is going to SUE his accuser

We reported yesterday that Chris Brown was accused of punching a woman in a Las Vegas night club, but now it seems the tables have turned as Chris is planning to SUE the accuser.

A source close to Chris told TMZ that the pop star will be filing a lawsuit against Liziane Gutierrez, the woman who claims he punched her in the eye.

Liziane went to the police after Chris allegedly punched her and made a statement for assault. But now, TMZ is reporting that Mr Brown is going to file a defamation suit against her today.

Chris is also said to be trimming down his friends list and won't let anyone who brings "random girls" into his parties anymore. 

It is also claimed that Ms Gutierrez also went after Jason Derulo a while back after he left her on the sidewalk outside a Hollywood nightclub. She told TMZ a week after the party that Jason tried to "get it on" with some ladies at the party, who later left crying.

We're not sure who to believe with this one!
