It finally happened. Taylor Swift showed off her amazing, slim bikini body and mysterious belly button(!) while vacationing with the band Haim in Hawaii on Friday, Jan. 23.
The "Shake It Off" singer, 25, posted several photos of her fun boat excursion via Instagram. She donned a colorful yellow and red two-piece and later slipped into a retro one-piece.
"Greetings from Maui! @haimtheband," she captioned one shot with sisters Este, Danielle, and Alana Haim. The group also went hiking and frolicked in the water.
"Hiking with the Squad in Hawaii. @haimtheband," she captioned another shot. "Este-back ride."
In one sexy pose, Swift bundled up in a blouse as she and her girlfriends tried to catch a tan. "When we were whale watching and didn't see whales for 5 minutes and got all moody," she joked.
Swift's rare bikini shots may come as a surprise to fans, but not as much as her revealing her belly button. (Yes, it's true!) Back in November, the "Style" singer told Lucky magazine that she doesn't like showing that part of her body.
"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 the mag. "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."
