First it was Superhead, and then Nas' ex Carmen Bryan, and now R&B singer Ray J is the next with a tell-all book about his sexual conquests.

According to AOL's Black Voices, the 26-year-old singer is in the final stages of completing his memoir, tentatively titled Sex Machine.

The book is reportedly due for release in the spring of 2008 via Karen Hunter Publishing/Pocket Books, and will take readers through Ray J's rise to fame and infamy.

He first rose to fame as an actor and singer, appearing on his sister Brandy's hit sitcom "Moesha," but early this year his internet stock spiked with the release of a leaked sex tape featuring him and socialite Kim Kardashian.

AOL reports that Ray J is rumored to have had sex with more than 1,100 women -- being romantically linked to Whitney Houston, Lil' Kim and fellow author Karrine Steffans (a.k.a. Superhead).

The book will document his family affairs -- including his sister's fatal car crash and a "full exploration of his sexual prowess dating all the way back to his first experience at age 10."
