One's "raunchy" and the other's a "dried up old whore." According to each other.
The catfight between Chelsea Handler and Jenna Jameson has just gotten nasty, with Jameson retracting her claws on Twitter in response to Handler's talking smack about the porn queen in last month's Glamour.
"Chelsea Handler makes fun of people's kids...Probably because she's a dried up old whore," Jameson tweeted yesterday.
Probably not the best idea to attack a comedian with a nightly platform for revenge.

"Just cuz I say it like it is," Jenna defended her comments in a follow-up tweet. "Don't hate...She talks massive s--t. Ok, whatever...."
The beef between the gals started last month when Handler mentioned Jameson in an interview with Katie Couric for Glamour mag, in which she called the married mom and ex-porn star "raunchy."
"I don't like the word raunchy. I'm irreverent and I say things that a lot of people wouldn't say, and some of it probably isn't in the best taste," said Handler. "But when I hear the word raunchy, to me that describes Jenna Jameson. Look, I'm never going to please everybody."
And for the record, Handler draws the line at making fun of kids.
"I think talking about children and their looks is not nice. Like, unattractive children. I don't do that. And I don't talk about people who are dying. I think that's inappropriate."
Chelsea's last public catfight was aimed at Angelina Jolie, when the talk-show host went on a verbal rampage in December and dropped the C-bomb on Brad Pitt's better half.
"She's a homewrecker, she is," Handler had ranted. "She can rescue as many babies from as many countries as she wants to, I don't f--king believe you.
"Because when I look into a woman's eyes and she gives interviews, and she goes, 'Oh, I don't have a lot of female friends'...'cause you're a f--king c--t, that's why. That's why. You're a female and you don't have female friends, you're a f--king bitch."
No tweets back from Handler just yet. We say tune in to Chelsea Lately to see her response.
