Caitlyn Jenner is showing her gratitude to one of the doctors who performed her facial feminization surgery.

The reality star signed a copy of her Vanity Fair cover for Dr. Harrison Lee, posing alongside him in a sweet Instagram shot posted by one of Lee’s employees.

“To Harrison, Great Job Thank you so much Caitlyn Jenner,” she wrote.

Jenner previously admitted to having a bit of a panic attack following the 10-hour surgery, thinking, “What did I just do? What did I just do to myself?”

But in the end, she didn’t regret it. “If I was lying on my deathbed and I had kept this secret and never ever did anything about it, I would be lying there saying, ‘You just blew your entire life,’ ” she told the magazine.
