R&B singer Ray-J (who happens to be Brandy's little brother) is putting the finishing touches on his memoir, tentatively titled Sex Machine. The narrative, due out this spring, will recount Ray-J's industrious sex life, including his relationship with Hollywood socialite -- and co-star in the crooner's hard-core adult video -- Kim Kardashian. The sex tape surfaced online in March of this year, but Kardashian took legal action to stop distribution of the tape in May.

Ray-J, 26, who has been romantically linked to Whitney Houston, Lil' Kim and fellow author Karrine Steffans (aka Superhead) over the years, will also give details of escapades with more than 1,100 women. The memoir will also document Brandy's recent legal troubles stemming from a fatal car crash, along with a full account of Ray-J's first sexual encounter at age ... 10?!
