The Keeping Up with the Kardashians matriarch revealed her cast Thursday while tweeting about friend Chrissy Teigen's new cookbook Cravings.
"I've waited with excitement for this fabulous cookbook to come out @chrissyteigen!!!" she captioned a photo of the supermodel's book cover.
"OF COURSE the day I get mine is the same day I have hand surgery so I can't cook!!!!" she added in another tweet.
Jenner, 65, is no stranger to the culinary industry: The momager published her own collection of family recipes, In the Kitchen with Kris, in October 2014.
A pregnant Teigen, 30, has been spending quality time with mom of two Kim Kardashian West as she await the arrival of her first child with husband John Legend.

The pals and Kanye West (plus 2-year-old North West) shopped at baby boutique Bel Bambini over the weekend, and Teigen is following the reality star's maternity style advice.
"I always wanted to be the person who showed off the bump because it looks beautiful and I think you should embrace it," the FABLife host told InStyle Australia recently. "Kim does that well, and I love seeing that belly of hers and I know Kanye does, too – we're lucky to be with men who find pregnancy sexy."
