Bruce Jenner claims the biggest lie he ever told was about his "golf score".
The reality TV star's life is documented alongside his wife, step-children and children in Keeping Up With The Kardashians.
Bruce has revealed that he's open and honest at all times - except when it comes to his sporting achievements.
"I don't lie! I've got morals..." he teased in an interview with British magazine Heat before revealing: "Probably a golf score".
The former Olympic athlete admits that he regularly removes items from his dirty laundry basket to wear, despite having maids around the house.
Bruce has joked about how he decides on whether he should wear something.
"I'm a jock! Of course! I got a pair of shorts that I wore the day before to work out, and now I'm thinking, 'Can I get another day out of them?'"
Bruce also revealed his nickname at school - stemming from his athletic ability.
"I was the fastest kid in school and, with my last name being Jenner, I was The Jenerator!" he laughed.
