Kara DioGuardi has decided to dish about her experience as an American Idol judge.

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."

Fox announced DioGuardi's American Idol departure in September following several weeks of reports about her fate. 

"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-lived Idol-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.
