Ten minutes later she continued her rant and stated, "Chris Brown beat you because you're not pretty enough. No one wants to be your lover so you call everyone and their mother that I almost named my new dog Rihanna."

Rihanna later responded to the aggression on the social network writing, "Ya see what happens when they cancel Intervention,"

However Bynes continued railing and later wrote, "Unlike ur fugly faced self I don't do drugs! U need the intervention dog! I met ur ugly face in person! U aren't pretty u know it!"

The "She's the Man" actress was arrested on May 24 for disruptive behavior and for allegedly throwing a bong at a police officer. She was also caught with marijuana but Bynes denied the claims and stated, "I only smoke tobacco I don't drink or do drugs. I've never had a bong in my life! I need to get another nose job after seeing my mugshot! :D"

She later claimed that she was sexually abused by the police when she was brought to the mental institution and police station. She tweeted, "to say I wasn't offended being treated like a mental insane person/criminal on the night the cops illegally entered my apartment, found nothing, sexually assaulted me, then arrested me taking me to a mental hospital, then locking me up all night for no wrong doing us criminal on THEIR part. My lawyer and I are taking this mistake extremely seriously! You cannot illegally enter my apartment then take me to mental hospital without any grounds. I have never been so offended in my life. They found nothing criminal on me or around me, one cop then sexually assaulted me, so I'm suing for all of the above! I'll be happy when I get money compensation from the cop who assaulted me and NYPD for wrongfully arresting me and having me put into a mental hospital and jail overnight! I don't want to keep talking about it. My lawyer is taking care of it for me. My real friends don't talk about me on twitter."

She also accused her family of stealing money from her. She wrote, "Also, never trust or listen to a word any person from my family says to the press. I am suing them for money laundering/unethical manager work, I never signed a contract with them, and they had been stealing my money without me knowing, claiming they were managing me somehow when they have no right to act as if they did anything to help or enhance my career and I want $ back that I earned on my own. I'm 27 and don't like when press talks to my parents. My parents are almost 70 years old. We are no longer on speaking terms. I would rather them be homeless than live off of my money."
