Brody Jenner would father "all girls" if he could

He told 'Entertainment Tonight ': "[Fatherhood] is the greatest gift I've ever been given, for sure. It really is. I had no idea how much I would love it. And to be honest, having a girl, going into it, you're like 'Oh maybe I want a boy or a girl...' but once I had the girl, I was like 'I want more girls'. I would have all girls, they're just so much fun. She's the light of my life, she really is.

"It really has just been the best ever. She's just the cutest. She just melts me."

The former 'Keeping Up with the Kardashians' star is now gearing up to take part in 'Special Forces: World's Toughest Test' and admitted that his little girl was his inspiration to take part in the military-style challenge show.

He told TooFab: "I felt like she was one of the main reasons I kept going and going as far as I could go.

"Just the thought of her and her watching it ... and even one of the reasons I wanted to do it in the first place was 'cause of her, to have that memory of me.

"You have a couple hundred cameras filming you for two weeks straight, and you're in situations where -- she's gonna watch me cry, she's gonna watch me be vulnerable, she's gonna see a different side of me than what she sees in her home life, so I think she was one of the main reasons I did it in the first place."
