Katharine McPhee is saying “Sorry, Not Sorry” after haters slammed her 72-year-old hubby, music producer David Foster, for posting a bikini photo of McPhee. The caption on the photo? “What baby?” Singer-songwriter McPhee gave birth to the couple’s child, Rennie David Foster, just 10 months earlier. The photo in question generated a lot of comments on social media, but McPhee and Foster remain unapologetic.
