No PDA, please!
Erin Foster reacted hilariously to the steamy snaps of her father David Foster with his wife, Katharine McPhee.
“Report this,” wrote the “Barely Famous” alum.
Erin, 39, left the comment on her stepmother’s Instagram slideshow on Tuesday, featuring multiple photos of the “American Idol” alum, 38, making love and hugging the composer, 72.
“Poor man,” McPhee wrote on the upload. “Too bad he doesn’t get much attention.”
Jessie J responded to the post with heart emojis, while music director Tommy Mottola wrote, “David..Ua lucky guy my man.”
McPhee married the Grammy winner in June 2019 and they welcomed a baby boy named Rennie, now 1, almost two years later.
David is also the father of five daughters – Allison, 52, Amy, 48, Sara, 41, Erin, and Jordan, 39 – from previous relationships.
Erin and Sara, in particular, have poked fun at their father’s relationship with McPhee over the years.
“Have you ever done a side plank with your 37-year-old stepmom?” Erin wrote via Instagram Stories in April 2021. “I have.”
As for Sara, the writer called McPhee “Mommmyyy” via Instagram after David proposed to the “Country Comfort” star in July 2018.
Sara finds the Broadway star “very funny,” she told Us Weekly in February of the following year.
“Katharine keeps her mouth shut a lot,” she explained in the 2019 interview. “If I were her, I’d be taking down trolls all day.”
Erin helped McPhee fight trolls in December 2021 after the “Open Toes” singer was criticized for showing off her postpartum body in a bikini.
“If I can accept that my stepmom looks like this, you certainly should,” Erin joked at the time, asking Instagram haters to “let her live”.
The Los Angeles resident went on to write, “The photo” [my dad posted of her] had not been altered or filtered, and she has not undergone surgery.
“You can’t be ashamed of someone for feeling cute after a baby, whether she has stretch marks or a six-pack,” Erin continued.
