Lindsay Lohan's lawyer Shawn Chapman Holley resigned Thursday, according to TMZ.

Earlier in the day, Holley defended the actress, 24, saying Lohan's 90-day jail sentence was too harsh.

"Ms. Lohan and I are extremely disappointed in the sentence handed down by Judge Revel," she told in a statement. "We believe that the penalty is far harsher than what others would have received under similar circumstances. The reality is that Ms. Lohan, like most defendants, had to balance work commitments with court requirements. To be punished so severely for doing so, particularly in light of the fact that she substantially complied with each of her probationary conditions, is harsh and unfair. That said, Ms. Lohan is prepared to serve her jail time and to comply with the Court's orders."

Chapman also defended Lohan's manicurewhich included the message "F*** You."

"With respect to Ms. Lohan's nails, the fact is, the words could barely be seen by the naked eye," she said. "That a courtroom camera, purportedly there to accurately chronicle the proceedings, would use a telephoto lens to zoom in as it did to Ms. Lohan's fingernail is a commentary on the entire issue."

Lohan, who must begin serving her sentence July 20, has been Twittering that her human rights are being violated.

On Twitter, she wrote: "It is clearly stated in Article 5 of the U.N. Universal Declaration of Human Rights that.... No one shall be subjected to torture or to cruel, inhuman or degrading treatment or punishment."
