Well then. Brody Jenner apparently believes his youngest siblings are very knowledgeable about sex.

Brody said Kendall Jenner, 19, and Kylie Jenner, 17, are more than qualified to talk about sex, and in fact, he'd be proud of them if they landed a show similar to his own Sex with Brody talk show on E!.

"Do you seriously think they don't know what's up? They could teach me things!" Brody told the UK's Mirror Online.

In the process, Brody appeared to take a shot at their older sisters Khloe Kardashian, Kourtney Kardashian and Kim Kardashian. After all, his relationship with the Kardashian side of the family has always seemed strained and tense, as previously documented on Keeping Up with the Kardashians. His father, now known as Caitlyn Jenner, was in the middle of two families.

"I mean, look at [Kendall and Kylie]'s older sisters. Are you kidding me?" Brody explained, eventually circling back to why he'd be proud of the two girls for starring in a show about sex.

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

The former The Hills, Laguna Beach, Bromance and The Princes of Malibu star insisted he's been working on this project for almost 15 years, giving himself a pat on the back.

"I literally filmed it when I was like 17-years-old," Brody said. "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's show discusses "very taboo subjects which not a lot of people talk about."

He continued, "I do get a grilling and some of it can be uncomfortable -- but not as uncomfortable as when people write stories about me that simply aren't true!"

At least one thing is clear. Brody didn't watch Kim's sex tape with Ray J.

"No, absolutely not," he insisted. "I steered away from that!"
