David Foster’s Daughters Have Only One Issue With Katherine McPhee

David Foster and Katherine McPhee have been married for over a year, and now his daughters — Sara, Erin and Jordan Foster — have revealed they only have one problem with her.

In an interview with People magazine, it was revealed the big problem they have with the American Idol alum is her beauty.

“Our biggest issue with [Katharine] is how hot she is,” Erin quipped. “Her body is insane. When she comes over for family Sundays, I’m like, ‘Do not get in a bikini.’ My husband’s always like, ‘Kat, get in the pool!’ And I’m like, ‘Simon…’”

Apparently, all of their husbands “hang on the side ogling her.”

“Even my 2-year-old son [Otto],” Jordan added.

“Interestingly, the age difference has played a role in a positive way,” Erin said of David and Katherine. “Our dad comes from a generation where women are more passive. He is also passive about his feelings. Kat has really pushed him to open up. We could get into a fight, and then Kat’s like, ‘No, you have to pick up the phone, call your daughter back.’”

Well, we’re not sure it’s commonplace to ogle your technical “step mom,” but at least there’s love and peace in the family, right? LOL!
