KEY POINTS

  • Jennette McCurdy heard that her controversial memoir sold out in some places
  • She assured fans that her publisher was working hard to restock shelves as soon as possible
  • The retired actress suggested getting the audiobook version that she narrated herself

Jennette McCurdy couldn't believe the success of her controversial memoir "I'm Glad My Mom Died" a day after its release.

The 30-year-old retired actress took to Instagram Thursday to share her reaction to the news of her book selling out in some places just one day after it hit shelves. McCurdy shared a screenshot of Rolling Stone's report about her book's impressive performance on Amazon and accompanied it with a lengthy message for her fans.

"Hi everyone. I'm overwhelmed by the incredible reaction to 'I'm Glad My Mom Died.' I see in your posts and comments how emotionally connected you are to this – how you have laughed and cried and everything in between with me – and it's meaningful and fulfilling to me in a singular way," she wrote.

The former "iCarly" star added that she heard about the hard copy of her book selling out in some places. She assured fans that her publisher was doing everything in their power to restock shelves as soon as possible due to the high demand.

McCurdy suggested for fans who couldn't wait for the next batch of hard copies to check out the e-book or audiobook version of her memoir because she narrated it herself "with my stuffed animal meatball in my lap."

In the Rolling Stone article that the former Nickelodeon star shared, the outlet revealed that "I'm Glad My Mom Died" quickly soared to the top of the bestsellers charts online before the physical copy sold out on Amazon, Target and Barnes & Noble altogether.

The book centers around the abuse McCurdy suffered from her late mom, Debra. However, the "Sam & Cat" star also made some shocking revelations in her tell-all, including the manipulative and inappropriate treatment of child stars at Nickelodeon and the moment that "broke" her while working with Ariana Grande.

Earlier this week, McCurdy learned that her book got included in Amazon Editors' Best Biographies & Memoirs of August. She celebrated the milestone by posing in front of a billboard featuring her book as one of the retail bookstore's top picks and sharing the photos online.

Fans quickly showered her post with compliments and congratulatory messages. One wrote, "You look so happy, we're all so proud of you." Another added, "Congratulations!!! So cool."

"I'm Glad My Mom Died" came out on Aug. 9.
