Ronson vs. Rivers: Defending Lohan

Samantha Ronson and Lindsay Lohan may not longer be an item, but that didn't stop the superstar DJ from defending the honor of her ex-girlfriend against attacks from comic legend Joan Rivers.

Rivers, known for her salty sense of humor, has been tweeting up a storm about Lohan since she was found guilty and sentenced to time behind bars last week.

Rivers has tweeted: "Lindsay Lohan is so dumb. Her idea of being sworn in is cursing at the judge,"

"I was just reading about the new Lindsay Lohan diet, which is all liquid. 80 proof"

"Lindsay Lohan had 'F-ck you' painted on her nails. What people don't know is that the judge had 'Eat me you party skank,' painted on hers."

Samantha Ronson responded: "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."

Lohan saw the tweet and responded with a simple "thank you."
