Judging by the many photos that she posts of her two young children, Jessica Simpson is one proud momma! But a recent photo with her 5-year-old daughter Maxwell is garnering major criticism on Instagram.
The 37-year-old pop star shared a photo of herself and her daughter inside a MAC store pouting their lips for a mirror selfie. Maxwell, who picked out her own lipstick shade, is seen wearing a dramatic, merlot-hued color.
"This is NOT an #ad, is my daughter's favorite store! Mommy-Daughter Day with #MAXIDREW #girlygoth," Simpson wrote in the caption.
But the mother-daughter photo sparked eyebrow-raising remarks from her fans, who claimed her daughter was "too little" to be putting on makeup.
"Her favorite store?? OMG. She should be playing outside or learning about the world not sitting in a chair putting on make up at MAC. What's wrong with you," one Instagram user wrote.
