(Cover) - EN Showbiz - Russell Brand was worried about upsetting Kate Moss with his second autobiography.

Despite being happily engaged to pop star Katy Perry, British funnyman Russell is famed for his womanising ways in the past, which he documented in his tome My Booky Wook.

The star is now back with the second part of his life story Booky Wook 2 which deals with the more recent period where he shot to fame and became a successful actor/comedian.

One of the most talked-about episodes in the autobiography is a passage where Russell describes the brief romance he enjoyed with the British supermodel back in 2006, and Russell has revealed he was anxious to respect Kate when he was describing the event.

"I thought when I was writing it, 'I don't want her to be upset when she reads it'. I thought if I said something that was intimate then that would be bad, he told the British newspaper The Sun. It was more like an encounter with an angel.

The 35-year-old was very complimentary of the beauty, saying that he was completely besotted by her.

I had a mad infatuation with her. I didn't feel all cool. It didn't feel like a conquest, it felt like I fell down a well, he gushed.

Russell admits he reverted to his childhood self around Kate, because he couldnt get over how beautiful she was.

"I was like a 12-year-old...I felt totally overwhelmed because she is obviously incredibly beautiful and she is Kate Moss, he added. (C) Cover Media
