Is Wayne worried???... Karrine "Superhead" Steffans says she's going to write a book about her relationship with Lil' Wayne -- and title it

"How to Make Love to a Martian."
Superhead says, "It won't be easy to write this, to go back and time and uncover a truth I haven't wanted to face. To remember the day we met, our first kiss, our first fight and the moment I realized I love him and the moment I realized he loved me."
No word on when the project will hit shelves.
