Brody Jenner said Tuesday that he would be proud of his sisters Kylie, 17, and Kendall, 19, if they ever made a sex show. The 31 year-old, who is promoting his new four-part series “Sex With Brody,” told the Mirror that his sisters are more than qualified to give him sex lessons.

"Do you seriously think they don't know what's up? They could teach me things!” Brody said, adding: "I mean, look at their older sisters (Khloe, Kourtney and Kim Kardashian.) Are you kidding me?

"I'd be supportive if that's what they wanted to do," Brody reportedly said, adding: "I'd congratulate them - especially if they did what I did and put an entire project together from beginning to end."

Brody also referred to a sex tape that he filmed when he was 17 and said that he has destroyed it.

"I literally filmed it when I was like 17-years-old," he said, adding: "I was a child and I got rid of it afterwards. I think a lot of kids that age have probably done the same. But I never had any intention of putting it out there."

Brody also talked about his new relationship with Caitlyn Jenner, formerly known as Bruce Jenner, and said that being around her is inspirational.

“She (Caitlyn) is a lot happier,” Brody said, according to Daily Mail, adding: “Bruce was covering a lot of secrets and you can always pick up on that with people. It's just awesome to see.”
