German rockers Tokio Hotel are writing a memoir detailing the first 25 years of their career.

Twin brothers Bill and Tom Kaulitz have inked a deal to pen their first autobiography, revealing they will be writing the book together.

Bill Kaulitz tells, "We're going to do that this year... I hope we have the time for it, because we really want to write it."

The siblings will each be writing their own individual excerpts for the memoir.

Speaking to his brother during the interview, Bill adds, "I think there are some stories you can tell better than me, and the other way around."
