The British comedian - who was at one time renowned for his womanising ways, before settling down with his pop star fiancee Katy Perry - took the supermodel back to his house in 2006 after being introduced to her by their mutual friend Sadie Frost.
Russell, 35, reveals in his new book 'My Booky Wook 2: This Time It's Personal': "When we arrive at Sadie's house it is decided that Matt Morgan, co-presenter of my radio show, should walk into the house, so there is no photo of me and her together.
"This gives me hope that we do have something to hide, but also makes me jealous of Matt as he gets to walk up the driveway with her.
"Within the beautiful house we flirt for a while, then under some mutual pretence of looking at hung photographs of Sadie's deplorably gorgeous children we wander off. We are alone.
"Eventually there is no more universe between our lips and so we kiss. And yes, on one level I'm enjoying the kiss, but my mind is screaming, screeching, body-popping, lambada-ing, every-dance-craze-there's-ever-been-ing.
"I get on with the kiss, and I think it's a good kiss, but of course all this analysis going on simultaneously.
"I've got to get her out the house. Ludicrously I say to her, 'Do you want to come back to mine Kate Moss?"
When Kate agreed to go back to his London home with him Russell admits it was one of the most exciting moments of his life, but also one of the most nerve-wracking.
Russell continues: "To be in her presence in my house doesn't make sense. It is a baffling fusion of the real and the imagined.
"It's like looking into the garden and seeing Vegas Elvis mowing the lawn, or going into the kitchen and finding Elvis in the Elvis Comeback Special '68 suit cooking up beans, or going into the bedroom and there's Golden Jacket Elvis from '54.
"Elvis, lying on my bed looking into my eyes. Elvis Presley has entered the building. Of course my mind will not shut up and let me enjoy the moment, there is an endless incessant narrative throughout it.
"The next day, ludicrously, I have to get up and live my normal life."
Russell's second autobiography 'Booky Wook 2: This Time It's Personal' is published on September 30.
