She’s been having a tropical girl’s trip with her Haim band friends.

And on a different bright day in Maui, Hawaii, 25-year-old Taylor Swift had fun splashing around in a striped bikini on a yacht.

The Shake It Off hitmaker, who previously declared that she wished to hide her belly button forever, flaunted her toned midsection in the attractive two-piece.

She also had no qualms about plunging into the freezing Pacific Ocean with her girlfriends, repeatedly swimming in and climbing back aboard the boat.

Her chic bathing suit had halterneck top with supportive padding to accentuate her curves and tie details on the bottoms.

At one point, Taylor and two of her pals put on goggles and snorkels and headed out to explore the crystal-clear seas.

The former country music icon is vacationing with Este, Danielle, and Alana Haim, fellow musicians who have been showing up in a lot of the blonde beauty’s recent Instagram photos.

Later, when she strolled along a sandy beach, the lanky beauty covered up with green shorts, a charming collared blouse with stripes in blue, and classic black Ray-Bans.

Taylor once stated to Lucky magazine, “I prefer not to expose my belly button,

That should remain a mystery for me. I haven’t shown anyone any sign of a belly button, as far as they can tell from my public appearances. It might be punctured. They are clueless. In the unlikely event that I get a large tattoo, it will be placed directly next to my belly button, where no one will ever see it.

Are there any hackers claiming to have “nudes”? You would adore that, I promise! After taking back control of her account, Swift wrote, “Have fun photoshopping cause you got NOTHING.”

The dedicated singer is making the most of her rare vacation time following an incredible 2014 that saw her career soar to new heights.

1989, her most recent masterpiece of pop perfection, has sold over 4 million copies and is expected to surpass the milestone set by her album Red.
