"She supports me. I see her every day," Bruce said on Monday. "We're doing absolutely great."
The 64-year-old's comments echo what his estranged wife Kris has said about their 22-year marriage coming to an end.
Despite remaining upbeat about the breakdown of his marriage, Bruce was less positive about the way he claims the media treat his children.
"Sometimes it's very difficult," said the former Olympic decathlete. "Sometimes they'll take some really, really tough shots at the family when they're not deserved and totally false, especially with my kids.
"I don't care what they say about me, but when they start ragging on my kids for things that they're not doing and totally misrepresenting them, that really, really bothers me to say the least."
He also discussed his famous stepdaughter Kim Kardashian saying she's "doing a great job" as mum to her and Kanye West's daughter North West. The step-grandfather added that he hadn't yet babysit the five-month-old baby girl.
The famously close knit Kardashian and Jenner families joined forces at the weekend for a charity yard sale near their Calabasas home.
Both Kris and Bruce were present for the fundraising event and were seen enjoying spending time with their children.
