David Arquette is frantically back-pedaling after he blabbed about his split with wife Courteney Cox on Howard Stern’s radio show Tuesday afternoon. He tweeted yesterday:

“I went on Howard Stern yesterday to provide clarity and honesty about what I’m experiencing but while doing that I shared too much… it’s alright for me to be honest about my own feelings but in retrospect some of the information I provided involved others and for that I am sorry and humbled.”

So, you’d assume he’s apologizing to his wife here, right? Think again. It seems Courteney knew he was going on Howard Stern, and they’d even discussed what he’d say beforehand. TMZ says:

Courteney Cox knew exactly what David Arquette was going to say to Howard Stern Tuesday, right down to the comment about having sex with another woman.

David and Courteney talked before his appearance on Howard’s radio show, and she was “fine” with what David would say.

No, it’s the mistress who’s pissed, because David told the entire world they had sex twice, and that’s a damn dirty lie. They actually fucked way more than that. TMZ adds:

The woman with whom David Arquette claims to have had sex with “once … maybe twice,” is indignant, telling friends, “Two times, my ass!”

Jasmine Waltz [claims] she had sex multiple times with David over the course of more than a month.

So, long story short, he’s publicly apologizing because he didn’t paint his mistress in a whorey enough light. You know, If he were any kind of decent, he would have just secretly videotaped her and put it on the internet. Chivalry just doesn’t exist in Hollywood anymore.

Who needs dignity when you have a plastic surgeon on speed dial:
