David Foster is aware that people keep talking about his 35-year age gap with wife Katharine McPhee but he doesn't really care: 'We think we have it pretty together'

• David Foster told People that he's aware that people discuss he and Katharine McPhee's age gap.
• The pair, married in 2019, are 35 years apart: Foster is 72 years old, and McPhee is 37 years old.

David Foster is aware that people talk about the age gap between him and his wife Katharine McPhee, who is 35 years his junior, but he thinks they have it "pretty together" in their marriage.

Foster, 72, and McPhee, 37, were married in June 2019. The pair first met in 2006 during McPhee's tenure on "American Idol," and maintained a friendship in subsequent years. In February 2021, the couple had their first child together, named Rennie David Foster.

"People always make the reference Kat and I with the age difference, but I've always said there's so many things that can bring a marriage down, and age difference is just one of them," Foster told People. "There's so many things that can go wrong. We think we have it pretty together."

While Rennie is McPhee's first child, he is Foster's sixth. His adult daughters Sara, Erin, and Jordan told People in 2020 that they don't have any issue with their father's marriage.

"Our biggest issue with [Katharine] is how hot she is," Erin, 39, told People, saying that McPhee had pushed her father to be "more emotional and more vulnerable."

Foster's daughters have joked about being the same age as McPhee in the past, with Erin once captioning photos of the couple "my parents" and "excited about my new step mom," months before they were officially dating.

McPhee recently defended Foster after he posted a photo of her in a bikini with the caption "What baby!" The caption drew criticism online, with some saying that Foster was "out of touch" and objectifying his wife's body.

"Stop being so offended by what people post who have zero impact on your life and move on," McPhee wrote in the caption of an Instagram post in response to the criticism. "Maybe you should have more of an attitude of like, let's say… 'oh that's nice he thinks his wife is hot.'"
