Caitlyn Jenner Praises Her 'Tough' Mother After Revealing Esther Broke Both Her Hips

By
Caitlyn Jenner must get her strength from her mother.
The I Am Cait star posted an Instagram pic from her visit with Esther Jenner, and in doing so, revealed that her mom had some health issues. 
"Visiting my mom and she's doing great after breaking both her hips," Caitlyn wrote. "She's been mobile -- she's tough."
A source close to the Jenner family tells ET that Esther broke one of her hips a while back and then the other one at a different time. The 89-year-old matriarch is now doing "surprisingly" well.
Esther has also exemplified kindness towards Caitlyn in how she's been supporting her child during her gender transition. After Jenner's big reveal in Vanity Fair, Esther admitted that she was adjusting to no longer referring to the 65-year-old former Olympian as Bruce.
"Think about it. It’s a difficult thing when it’s habit. But I will accomplish this," Ester told New York Daily News. "I love him dearly. It doesn't matter whether he dresses like a male or a female. Whatever he needs to make him happy that's all I care about."
