Steven Tyler's daughter is writing her memoirs! No, sorry, not Liv. That other one. The plus size one who was on The Simple Life The Surreal Life! She's writing a book called Creating Myself for S&S's ladylit imprint Atria, and there is a press release about it that's not so much breathless as it is oxygen-deprived. The book will be a "deeply coming of age personal memoir!" But that's not all. It will also recount Mia's troubled past. "On the surface, Mia Tyler would seem to have been born into a fantasy life as the daughter of a rock star and a glamour girl. But Mia spent nearly 20 years as a trouble-filled youth." How Jerri Blank! We can't wait to read it.
