David Foster and his wife Katharine McPhee have been married for almost three years now, but there are still a lot of criticisms because of their 35-year age gap. Recently, the famed singer spoke out about their relationship and revealed a shocking thing.

In a recent interview with People Magazine, the "Who's Gonna Love You Tonight" hitmaker shares a revelation behind their marriage, saying the public "always make the reference" about he and his wife's age gap.

The singer also noted that "age difference" is one of the "many things that can bring a marriage down."

However, despite admitting that "there are so many things that can go wrong," he later clarified that he thinks they "have it pretty together."

Elsewhere in the interview, Foster opened their parenting skills about their baby son, 11-month-old Rennie, saying the child has already learned a lot, so Katharine McPhee wanted to work full time again, but not with him.

"I'm really grateful to her that she just goes, 'OK, I'll grab the baby, I'll come out, and sing a few songs.' It's really great - she's a star," he added. (via Daily Mail UK)

Speaking about his experience as a father despite having five older daughters and grandchildren, the singer noted that he feels great being a dad.

He clarified that he loves all of his children equally as much as his son.
