Jenner posted news of the ending on Twitter.
After 2 amazing seasons of @IAmCait, it's time for the next adventure. Thank you E! & thank you to the best girlfriends I could ask for!— Caitlyn Jenner (@Caitlyn_Jenner) August 16, 2016
Rumors of the show's cancellation go back as far as last year after ratings for its Season 2 premiere plummeted to 745,000, down from the 2.7 million who watched the series premiere, according to The Hollywood Reporter. The news likely won't derail Jenner's Hollywood career though; she's been busy with other ventures including her own line with MAC Cosmetics. Most recently, she has been tapped to join the cast of Amazon's Transparent.
