The British funnyman - who was famed for his womanizing ways until he married the singer in October 2010 - had a ''bit of a reaction'' sexually and dated many women after filing for divorce from the pop beauty after 14 months of marriage.
He said ''[I had] a little bit of a reaction. Like if you've been on a diet of rice for awhile and then suddenly Willy Wonka said, 'I need you to run my chocolate factory.' I think, for a while, you'd be kicking over barrels of candy and swimming about in the chocolate river. That's not a euphemism!''
Russell - who confirmed he is now in a relationship with Isabella Brewster - also spoke about the ''great relationship'' he had with Katy's parents, pastors Keith and Mary Hudson.
He told Howard Stern on his Sirius/XM radio show: ''They were lovely. We had a really great relationship actually. When you say that they are Christians, they are not... stiff. Her dad came from sort of a crazy background, and her mom went to Berkley in the sixties. They were more born again Christians, so I think they kind of identified with me.''
