Chris Brown I'm On the Attack Now I'm Suing My Accuser

EXCLUSIVE

0103-chris-brown-liziane-gutierrez-TMZ-02Chris Brown has a warning to anyone who makes false allegations against him ... no more Mr. Nice Guy. He'll be suing you.

Sources close to Chris tell us, he will be filing a lawsuit against Liziane Gutierrez, the woman who claims he punched her in the eye at a Vegas hotel.  She filed a police report and made statements to others about the alleged incident.  We're told Chris will be filing a defamation suit against her, as early as tomorrow.

Brown, we're told, is taking other steps ... for starters he's cutting out the "hangers-on" who are inviting "random girls" to hang out with him.  He says this is the second time he's been falsely accused of abuse by party girls and he's putting a quick end to it.

As we reported Gutierrez also went after Jason Derulo after he left her on the sidewalk outside a Hollywood club and invited her friends to an afterparty at his home.  She told TMZ a week after the party that Jason tried doing untoward things with the girls, who left the party crying.  

Gutierrez refused to substantiate her accusation with a single example.  Chris says  it's proof she's just a bitter woman who lies when she doesn't get her way.
