Katharine McPhee defends comments from her husband, David Foster, about her post-baby body: 'I cannot with this oversensitive society'

• Katharine McPhee Foster addressed the criticism of her husband's comments on her post-baby body.
• On Tuesday, David Foster posted a photo of her in a bikini with the caption, "What baby!"

Katharine McPhee Foster told those who criticized a post from her husband, David Foster, about her post-baby body to "get a life" in an Instagram post Wednesday.

On Tuesday, Foster posted a photo on Instagram of his wife, who gave birth to their first child in February, wearing a bikini, captioning it with a treble-clef emoji and the text, "What baby!" The caption drew criticism, with some commenters saying that Foster was objectifying his wife's body and calling his comments "out of touch," Yahoo Life reported.

McPhee Foster's post Wednesday addressed those criticisms, calling the media attention on her husband's comments "so dumb."

Accompanied by a photo of herself in a red swimsuit, the "American Idol" alum, who is 37, said she "struggled with weight" throughout her 20s and 30s, during which time her weight fluctuated.

"I lost this baby weight without dieting," McPhee Foster wrote. "Diets are the worst and I've had zero pressure from anyone. I've let my body do its thing and found a great workout. That's it."

The two got married in June 2019 and had their first child, Rennie David Foster, together in February.

McPhee Foster, who has spoken publicly since her 2006 "American Idol" run about dealing with an eating disorder, told E News in October that her pregnancy helped her be at "peace" with her body and gain a "huge appreciation" for what it was capable of.

"I actually had this huge gift where I felt zero pressure to kind of get back to a certain standard," she told the outlet at the time. "I was just like, 'Wow, this is such a moment in time to enjoy a new baby and give thanks to this incredible body that just did something so spectacular, like truly a miracle.'"

In her Instagram post, McPhee Foster said she "cannot with this overly sensitive society right now," closing it out with a Taylor Swift quote.

"Haters gonna hate," the actress wrote.
