My little labor of love this year 🥰 #BIRDIEMAE

While the majority of the 38-year-old star’s 4.8 million Instagram followers responded with variations of “aww!” and “cute,” one person decided to draw attention to one particular part of the photo — which actually proved to be an optical illusion.

In fact, the troll apparently thought a little something on the edge of Simpson’s scoop-neck shirt was something that it wasn’t, writing “#thefappening #nipslip,” in a comment.

Simpson, however, took aim and served back a hilarious response.

“I think it’s flattering that you think my nipple is that high up,” she quipped.

Shortly after delivering Birdie via C-section in March, Simpson opened up about struggling with her recovery from the surgery.

“Recovering from a C-Section is no joke!” she wrote. “I’m feeling thankful for these two older siblings looking over their new baby sister. I think we all get so carried away with the excitement of having a new baby that we forget that we are going in for major surgery. Then on top of that, we get home from the hospital, have to recover from the surgery, balance our new life as a parent to three kids and be a wife.”

Recovering from a C-Section is no joke! I'm feeling thankful for these two older siblings looking over their new baby sister. I think we all get so carried away with the excitement of having a new baby that we forget that we are going in for major surgery. Then on top of that, we get home from the hospital, have to recover from the surgery, balance our new life as a parent to three kids and be a wife. I'm so grateful to the @peanut community for helping me tackle this new life and supporting me as a mother of three! The @peanut app is an amazing support to connect with other moms and get advice. The app introduces you to women in your neighborhood based on the things you have in common. I have been chatting with other moms in my same situation and they have been answering my questions. It is so nice to be able to relate to a community of moms and moms-to-be who are going through the same things as me. Go check it out. #peanutapp
