If there’s anyone who can get Russell Brand to spill on his ex-wife Katy Perry, it’s Howard Stern.

That’s exactly what happened on Monday.

While on Howard’s Sirius XM radio show, Russell got pretty candid when the host asked his thoughts on Katy’s relationship with John Mayer.

And, well, the 37-year-old comedian certainly did not hold back. Check out his 5 most shocking comments about his ex-wife and her dating life below:

If John’s a Worse Womanizer Than He:
“Worse or better, depending on how you view it.”

He Quickly Admits He’s A BETTER Womanizer After Howard Says He’s Not:
“Hold on, I resent that! I’m world class!”

All in All, He Doesn’t Care:
“You have to let go of the instinct to protect someone once you divorce them.”

And He Won’t Give Intimate Details About Katy:
“So help me, Howard Stern, I will not compromise my ex-wife’s vagina for the sake of ratings! That woman was perfect from top to bottom!”

So Is He Dating Anyone?
“I’m not dating anybody. Actually, I’d like a romance. Not so much playing the field, just going through life, meditating, doing yoga, concentrating on this TV show and trying to find a nice wife.”

One of our favorite parts from the interview? The fact that he intends on romancing Demi Moore — someday.

“I really like her, she’s a beautiful person,” he shares. “I’ve not made love to her yet, Howard, but it’s a matter of time.”

Demi and Russell — now that would be interesting.

What do you think of his new interview? Do you think it’s funny or a little too much?
