Madison, who is expecting her first child with boyfriend Pasquale Rotella, took the photo in her bathroom while wearing a gray shirt and black pants. The pregnant star lifted up her shirt to her chest to reveal her decorated belly. The Peepshow dancer painted a giant smiley face (featuring long eyelashes and plump red lips) on her baby bump.
"Hey guys! I took this pic of the baby bump this morning -- smiling just for you!" she captioned the shot. "Hope you're having a great weekend."
"After becoming pregnant, I had to makeover my pantry just a little to make the proper adjustments to support the baby," she wrote. "I've found some staples that will stick around after the baby is here, too."
Some of her favorite snacks include apples, smoothies and flaxseed.
