Amanda Bynes claims her Rihanna bashing tweets were fake.

She wrote: "I saw a bunch of mocked up tweets about me bashing Rihanna in my mentions. I'm followed by so many people that someone is always mocking up fake tweets so I feel the need to address them!"

Amanda, who was charged with attempted evidence tampering, reckless endangerment and marijuana possession in court last week, after being arrested at her New York City apartment, then went on to blast Rihanna for allegedly smoking marijuana.

She added: “"That's one of the mocked up images, they took photos of me from outside and morphed them onto someone else's body. I am allergic to marijuana and alcohol but I smoke tobacco. Why does Rihanna smoke weed and not get in trouble for it but I smoke tobacco and people think I'm on drugs? I refuse to be treated like someone I'm not, which is why I fought for myself and am suing everyone involved. I don't need to go to rehab. There is never a drug or alcohol in my system! I'm sick of all the lies! What would you do if someone accused you of things you didn't do and yet you still had to be in jail at all over it! I'm so offended but I am so educated that I know cops cannot illegally enter my apartment, sexually harass me, arrest me, take me to a MENTAL HOSPITAL, then lock me up for a crime I didn't commit. I'm suing them all for this upsetting nightmare. My lawyer knows I'm a model citizen who doesn't partake in drugs. He's going to court this week to set the record straight again on my behalf. Thankfully I'm an educated multi-millionaire who knows better than to speak to perverted unjust cops without my lawyer (sic)."
