Lindsay Lohan Slams at Joan Rivers on Twitter

Actress Lindsay Lohan isn't obviously pleased with her 90-day jail verdict and totop it all off, she's not enthusiastic with what certain people have to comment about her predicament.

When Joan Rivers brought it on Twitter to criticize the actress posting that Lohan,24, was "so dumb" and that the "new Lindsay Lohan diet is all liquid. 80 proof" Lohan will not keep mum about it.

Lohan tweeted on Tuesday, "Joan Rivers and her 'stargument' make me believe that she and Michael Lohan are a match made in heaven," saying something  about the comedian and her dad, with whom she's had a rocky relationship.

Then she made another tweet,"All he needs is her botox doctor. 'Dr.' Drew – any ideas? Botox rehab reality show?"  aiming at Celebrity Rehab's Dr. Drew Pinksy, who once said the star needed to get arrested in order to get help.

"Thanks @lindsaylohan sounds like a terrific plan! Actually happy to see you have retained your sense of humor despite your circumstances," he responded, while also thanking fans who took offense to her use of quotes around his "Dr." title.

As a finale,Lohan later tweeted: "In the words of 50 cent,You shouldn't throw stones if you live in a glass house and if you got a glass jaw, you should watch yo mouth"

Lohan's Attorney Resigns

Lindsay Lohan is definitely in for a more legal drama.

Just hours Thursday afternoon, after Lohan's attorney Shawn Chapman Holley released a statement calling the star's 90-day jail sentence "harsh",  Holley all of a sudden resigned as Lohan's lawyer.

A representative for Holley confirmed the lawyer is no longer representing Lohan, but would not release any more details.

But it seems Lohan may have already have a new attorney in her criminal case, according to police.

"We got a call yesterday from a female identifying herself as Tiffany Feder-Cohen," says L.A. Sheriff's spokesman Steve Whitmore. "She introduced herself as Lindsay Lohan's new attorney. I can't get into details about why she called, but the bottom line is that we at the sheriff's department only do what the courts instruct us to do."

Calls to Feder-Cohen's office were not returned.

"Lindsay is determined to not go to jail, get new attorneys and just appeal it," says a source close to the actress. "She seems totally with it, smart and knows what she wants."

However a legal expert says the chances of winning an appeal are slim to none.

"There is absolutely zero chance of Lindsay winning an appeal because there's overwhelming evidence of her repeatedly violating her probation and the court's orders," says criminal defense attorney Trent Copeland, who's not involved with the case. "That is undisputed."
