Howard touched on John's seductive ways, asking Rusty if he was concerned about her. "Doesn't she know that [John]'s a worse womaniser than you?" he asked.
Always one for perspective, Russell replied, “Worse or better, depending on how you view it. Hold on - I resent that! I'm world class!"
When asked to dish some gossip on Katy's woman-bits, however, Rusty flared up. Check out his reaction in the clip above! Take that, Howard Stern!
In truth, it sounds like Rusty has been trying to distance himself from Katy emotionally, adding, "You have to let go of the instinct to protect someone once you divorce them." Ain't that the truth.
Katy divorced Russell last year and neither waited too long to move on. While Rusty's been linked to a few women, including Spice Girl Geri Halliwell and even an Aussie TV presenter, Katy appears set on John for now.
At the moment, Rusty's going through a lady-drought. "I'm not dating anybody. Actually, I'd like a romance," he said. "[I’m] just going through life, meditating, doing yoga, concentrating on this TV show and trying to find a nice wife."
