Caitlyn Jenner's boobs have Kim Kardashian feeling envious!

On Sunday's Keeping Up With the Kardashians, Kim tells her sister, Khloe, about a time recently when she helped the 65-year-old Olympian change her outfit.

"I went into the closet and she went to change and she was like, ‘You can stay in,' and took off her top and had no bra," Kim reveals. "Her boobs were like Kourtney's like when she first got hers done. Like, it made me want a boob job. Like, the best boobs."

"She has full implants?" Khloe asks, before Kim reveals. "A full boob job. Like a C."

"While I felt like I looked great and that the gown looked fabulous, I still have a voice issue," she wrote. "It’s not quite right compared to my feminine appearance. That bothers me a little bit. However, I hope that people don’t listen to the pitch of my voice, but listen to what I have to say. That’s important to me."
