Russell Brand spoke about ex-wife Katy Perry and shared his opinion about her new boyfriend, John Mayer.

The comedian was asked (by Howard Stern):   "What do you make of your ex-wife dating John Mayer?  Doesn't she know that he's a worse womanizer than you?"

Brand replied, "Worse or better, depending on how you view it. He's a better womanizer, then. Hold on, I resent that!  I'm world class!"

He didn't want to say a bad word against Mayer, though, explaining, "You have to let go of the instinct to protect someone once you divorce them."

Brand did say, "So help me God, Howard Stern, I will not compromise my ex-wife's vagina for the sake of ratings! That woman was perfect from top to bottom!"

Brand also admitted that he'd like to find someone new, but right now he's focusing on himself. Read more at US Weekly!

** He denied rumors that he's been dating Demi Moore.  Brand joked, "I really like her, she's a beautiful person. I've not made love to her yet, Howard, but it's a matter of time. That's the sort of thing that'll get in the newspaper."
