Rapper T.I. writing relationship book with wife

Rapper T.I. and his wife Tameka 'Tiny' Cottle have teamed up professionally to pen a new relationship self-help book.

The "Live Your Life" hit-maker, real name Clifford Harris, Jr., is making his literary debut this week, Oct. 17, 2011, with the release of "Power & Beauty: A Love Story of Life on the Streets" - about two childhood friends torn apart by shady dealings on the streets of Atlanta, Georgia.

T.I.'s already nearing completion on its sequel, with co-author David Ritz, and he's planning to write a third book too.

He tells XXLmag.com, "We’re right at the end of (Power & Beauty II) right now. We’re trying to figure out how to end two and begin three."

And the hip-hop star has revealed he is also working on a self-help book with his wife, former Xscape singer Tiny. In the tome, the couple will share its love advice with readers.

T.I. adds, "Tameka and I, we looking to do (a) his-and-her (sic) relationship book; how to get right and keep it tight."

The couple has been dating since 2001 and wed last year (2010).
