HarpersCollins Publishers has confirmed that it will release "A Helluva High Note: Surviving Life, Love, and American Idol," a memoir written by DioGuardi, next spring.
Released by the publisher's It Books imprint, the 224-page hardcover will go on sale on April 26 and cost $24.99.
According to RadarOnline, DioGuardi -- a successful songwriter who joined American Idol in 2008 and served as a judge for the reality competition's eighth and ninth seasons -- claims the book "is meant to inspire others to take chances to succeed."
"I felt like I won the lottery when I joined American Idol two years ago, but I feel like now is the best time to leave Idol," DioGuardi said in a press statement at the time.
Prior to serving as a member of Idol's eighth and ninth season judging panel, DioGuardi also served as a judge for The One: Making a Music Star, a short-livedIdol-like singing competition which aired on ABC in Summer 2006.
Earlier this fall, Bravo announced DioGuardi will serve as the head judge of Going Platinum, a new reality competition for singer-songwriters.
Going Platinum -- which will also feature recording artist and former Nashville Star host and judge Jewel on its judging panel -- is currently in production in Los Angeles and scheduled to premiere in 2011.
