MAUI, HI (KTRK) -- Taylor Swift apparently does have a belly button. The pop star, known for not showing that part of her body, released a photo via Instagram of herself and her friends vacationing in Hawaii wearing bikinis.

And lo! There is Swift's belly button.

Swift told Lucky magazine back in November, "I don't like showing my belly button. When you start showing your belly button then you're really committing to the midriff thing. I only partially commit to the midriff thing-you're only seeing lower rib cage. I don't want people to know if I have one or not." She laughs. "I want that to be a mystery. As far as anyone knows based on my public appearances, they haven't seen evidence of a belly button. It could be pierced. They have no idea. If I'm going to get some sort of massive tattoo, it's going to be right next to my belly button because no one's ever going to see that."
