Katharine McPhee, 36, retaliates against the troll who claimed she married David Foster, 71, because of his money

Katharine McPhee struck back at the trolls who claimed she was married only to her husband David Foster because of his money.

The 36-year-old singer took to Instagram on Sunday to wish her other half, 71, a happy Valentine’s Day, but while she was delighted to celebrate the occasion, some critics found it necessary to troll her age difference.

The backward photo of her with David showed them enjoying a day at the beach, and she looked stunning in a red bikini while he kissed her neck.

She wrote: ‘My forever Valentine !! My best friend, my favorite person, my motivator, my day to day! @davidfoster I looove you cookie. #Happy Valentine’s Day’

However, a troll knocked on his writing: ‘There for the money’, in response Katharine simply replied ‘obviously’.

However, not everything was negative, as David’s daughter, Erin, shared a funny comment that the photo was ‘a little sexual for me, but cute’, which amused Katharine as she responded with laughing emojis.

In another exchange, a Katharine fan said to her: ‘I bet you posted this photo crying for your body and missing you’.

She told them she was not ‘because I’m wearing red’, but a different fan criticized the commentator for his remark about her figure, criticizing them for his ‘horrible and stupid’ message that they saw as a body shame.

The first fan stated that he had not shared the comment to ‘make her feel bad’, and Katharine assured them that no, while she replied: ‘Actually, I understand. I liked the comment. ‘

McPhee officially confirmed her pregnancy on Instagram in December with a selfie in the mirror of her belly wrapped in a baby blue overcoat, which she took off her shoulder.

She seemed to imply that she is going to have a boy, not just in the color of her coat, but with a blue butterfly emoji framed by two blue heart emojis in the caption.

The actress House Bunny hinted at her pregnancy for the first time in October, taking to her Instagram Story with a gift from the Italian aperitif brand Aperol.

She said in the unboxing video, ‘I’m not going to drink this for a while. Flasher. But I am so excited. ‘

It happened just days after a source told People that she and Foster were expecting their first child together.

Another source told Us Weekly in August that the couple was “definitely trying” to have a baby, and their daughters “are expecting [McPhee] having a child and fully supporting him. ‘

Foster has five daughters from previous relationships, including Allison, 50, Amy, 47, Sara, 40, Erin, 38 and Jordan, 34.
