Taylor Swift does have a belly button and yes it’s adorable. The “Shake It Off” singer showed off her bikini body while vacationing with the band Haim in Hawaii in a series of snaps on Instagram.  Swift and the trio of sister, Este, Danielle and Alana Haim posed for several photos while hiking and boating.

The 25-year-old singer’s bikini shots may surprise fans because she had previously confessed to not wanting to show too much skin.

"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. I want that to be a mystery," she told Lucky magazine. "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."
