Announcing her upcoming project via Twitter, the 28-year-old actress promised her fans that the book would be released next year in spring.
"Can't wait until next spring! So many juicy stories about my life. Glee, guys, growing up & much more. #sorrynotsorry," Rivera wrote on the social media.
She added a screenshot of an article about her book deal announcement alongside the message.
"Sorry Not Sorry" will chronicle Rivera's story of her early days as a child star when she appeared on "Family Matters" and "The Fresh Prince of Bel-Air" in the 1990s.
