London, July 3 :  Singer Rod Stewart's wife wore a short dress to keep him interested when she had to photograph him for his autobiography.

Photographer-and-model Penny Lancaster shot the cover image for his new book and she decided to squeeze into a revealing dress as she knew it would keep Stewart entertained during the session.

"It was quite a hot day and there was a fan blowing, which lifted up my dress a little. I'd deliberately worn something short, because as everyone knows, Rod's a leg man," femalefirst.co.uk quoted Stewart as saying.

"Got to keep my darling happy. In other words, the mood was fun and friendly and relaxed, which seemed to produce the best results," she added
