"Kim and Kanye have done this all on their own and they've had the best time planning it and I know nothing," said the 58-year-old reality star.
"I have not seen her wedding dress," she continued. "I don't know how she looks in it. I'll see it for the first time when she puts it on at her wedding."
Jenner added she was excited to just be able to relax and "let everyone else worry" about everything because she's "such a control freak."
"I'm going into this with a great deal of excitement," she said. "I was a little bit curious at first and now I'm just like OK, just let it go, breathe and enjoy."
Asked about her other daughter Khloe Kardashian and her relationship to singer French Montana, Jenner said the two were "just friends."
"They're hanging out," she said of the duo's multiple outings.
