The 34-year-old was also called out for her “inconsiderate/tasteless” choice to wear a cross in the image, but she wasn’t taking the hate lying down.
The actor shared some of the crappy comments she’d received in an Instagram story, and added some wise words for her trolls.
“Two kids, a couple of emergency ops and a necklace in memory of my abuela. GRATEFUL. FOR. IT. ALL.” she wrote in response.
“Scars. Saggy skin. Stretch marks.”
Plenty of her fans have shared their support, calling out the original offenders.
"Geez if my stomach looked that "weird" I would be thrilled," one wrote.
"You look fantastic Pia and good on you for not listening to the haters! Your attitude is what young girls need to see!" commented another.
