Caitlyn Jenner said her kids look totally different when they go make up free.
The 72-year-old counts supermodel Kendall Jenner and make up mogul Kylie Jenner among her children, as well as being a step parent to Kim, Kourtney and Khloe Kardashian for a large part of their lives.
With many beautiful women around her, it would be easy to assume that they're the ones who taught her everything she knows.
Caitlyn was asked about her expert make up skills by her housemates, who joked they didn't need to ask who taught her how to apply it before remembering who her daughter is.


But Caitlyn said she had actually taught herself, and that she'd been secretly doing her make up since she was 10 years old and suffering from gender dysphoria.
The reality star said: "Actually my daughters asked me that question. I’ve been doing my make-up since I was 10-15 years old and nobody knew it.
"I used to buy magazines about make up and kind of study it, so I kind of learned that way. It’s amazing what you can do with makeup. I look at my kids and go, 'Oh my God it looks like a totally different person'."

Caitlyn was also seen on the show talking about her housemate Omarosa Manigault Newman, a former political aide to ex US President Donald Trump.
Caitlyn, who has been running for Governor of California, said: "The reason Trump liked her was because she was on The Apprentice. She was like this ballsy, backstabbing, and doing whatever she had to do to win, but boy it p****d a lot of people off.
"They all called me before I came down here and said 'Watch out for her'."
Talking about the secret recordings of Trumps conversations with chief of staff John Kelly that Omarosa released, Caitlyn went on: "And boy did she blow it.
"All of the people that worked at the White House are all working on my campaign. I know every little secret story behind everything, why she was kicked out.
"She went into a top secret secure area, you get checked for a recording device, you can bring nothing in there, she snuck something in and started recording. That was kind of the final straw."
