The notorious playboy has been linked to a number of hot young things since splitting with Katy in December last year, including a
Mexican artist and a Hungarian model.
Russell confirmed to US radio host Howard Stern that yes, he's officially dating actress Isabella Brewster now, but admitted to running rampant for a good few months before settling down with his new squeeze.
"[I had] a little bit of a reaction," he said.
"Like if you've been on a diet of rice for a while and then suddenly Willy Wonka said, 'I need you to run my chocolate factory'."
That's certainly one way of putting it, but we’re not sure Katy would appreciate the comparison.
Russell told Howard that he's over the sexual wanderings for the time being, though.
"I don't want porn anymore … there is no market for it in my life. I've got no kind of weird predilections especially."
The comedian joked about his bedroom antics with Katy, saying, "she was very willing to do wheelchair porn" before gushing about how much he adored his ex-wife.
"I loved her so much, it seemed like the sensible thing to do [when we got married]," he said.
But in a show of respect for the pop star, Russ was reluctant to let too much slip.
"I don't want anything to hurt her. She's younger than me, she's a young woman and she's beautiful and she's sensitive and I care about her deeply … She'll read it and she'll be sad and I don't want that," he said.
Naw. Underneath the playboy persona, it seems there could be a caring, sensitive guy.
