Headed to jail in one week, Lindsay Lohan has been lying low -- but that doesn't mean she'll take Joan Rivers' insults lying down.
On Tuesday, the 24-year-old star wrote a snarky set of Tweets bashing the comic's recent jokes made at her expense...and her estranged father Michael Lohan and Dr. Drew Pinsky came up, too.
"Joan Rivers and her 'stargument' make me believe that she and Michael Lohan are a match made in heaven," Lohan wrote.
"all he needs is her botox doctor. "Dr." Drew- any ideas? Botox rehab reality show?"
The Mean Girls actress added angrily, "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'"
Soon after Lohan was sentenced to 90 days in jail for a parole violation related to a DUI arrest, Rivers tried out a new Lohan comic bit via Twitter.
Lindsay Lohan is so dumb. Her idea of being sworn in is cursing at the judge," Rivers, 77, wrote, referring to Lohan's F-word manicure.
"I was just reading about the new Lindsay Lohan diet, which is all liquid. 80 Proof."
While Lohan initially ignored Rivers' taunts, her ex girlfriend Samantha Ronson defended her honor. "Hey Joan Rivers...You have collagen older than Lindsay, pick on someone your own age, oh wait I guess people that old can't hear."
