Australian supermodel Elle Macpherson's bedroom secrets are about to be revealed in a new tell-all book, according to a report in the US.

Macpherson, nicknamed The Body, is not the only focus of the steamy memoir.

Sex stories about other supermodels, including Paulina Porizkova, Andie MacDowell and Tatjana Patitz, will also be featured in the book.

So, who is the love rat spilling the beans?

According to the New York Post, former Calvin Klein male model Bruce Hulse is writing the kiss and tell book about his sexual exploits with some of the world's most beautiful women.

Silver fox Hulse, now 55, is married with two children, but that has not stopped him from penning the book Sex, Love and Fashion about his former bed-hopping days.

Macpherson, he wrote, "stripped down in front of me".

However, Hulse said he was depressed over a recent bust-up and lost his sex drive.

"She was so understanding ... 'No worries, Bruce ... Let's just be friends, then'," Hulse wrote.

But apparently Hulse wrote he overcame his problem and he and the Australian beauty hooked up for a one-nighter under his parents' roof, the Post reported on Monday.

The book is due to go on sale in August.
