The 30-year-old Internet sensation, who first gained attention thanks to her unbelievably fit pregnant body, recently faced Photoshopping accusations about this bikini pic with her son, 2-month-old James Hunter. Pointing out what appears to be a bump on her upper left thigh, some of her followers were quick to assume photo manipulation.
"Photo was altered to make her look skinny," one user writes.
However, Sarah tells ET this is absolutely not the case.
"The photo isn't Photoshopped," she says. "My husband took several photos and they all looked like that."
"It's hard to pose a newborn," she also points out.
Sarah even Instagrammed a second shot her husband took of her and their baby to answer her haters, writing, "When you're sharing a pic of a relaxing pool day with your son and people are concerned with your thigh shadow/pudge/skin."
Regardless of the naysayers, it's pretty safe to say Sarah looks great in her white bikini.
And yes, she still has those abs less than three months after giving birth.
