Amanda Bynes and her parents are ready for a fight. The troubled actress showed up at court on Friday to battle her parents and the judge, in yet another attempt to rid herself of her parents' conservatorship and prove to the world she is sane.

The hearing is Amanda's opportunity to convince a judge that she is mentally competent to have legal and financial custody over herself.

Despite her assertion that she is sane enough to make her own decisions -- the 28-year-old actress was late to her 1:30 pm court date in Ventura County, reports TMZ. Less than 45 minutes before the scheduled court time, the former What I like About You actress was spotted eating watermelon at Mel's Diner in Hollywood, which seemingly caused her to be late, reports the site. This definitely doesn't seem like the behavior of a person who is well ...

On Thursday, Bynes left the psychiatric facility where she had been for more than two weeks. Doctors had deemed her incompetent to live on her own, but a judge overruled the doctors' decision, saying she shouldn't be held against her will.

Since being released on Thursday, the Sydney White actress has been seen wandering the Sunset Strip, throwing fits and going on another epic Twitter rants.

Let's hope the judge does whatever is in Amanda's best interest ...

UPDATE: The judge shot down Amanda's request, and as a result her parents' conservatorship is still in place, reports TMZ. A lawyer, who said he represented the actress, came to fight for her independence in court today, however the judge ruled Amanda could not hire him because she was still under conservatorship and therefore did not have the capacity to enter into a binding contract. That means: the conservatorship stays.
