The 24-year-old singer has been documenting her trip to Maui on Instagram, where she's shared several photos of her trip alongside the all-girl rock band Haim, which is composed of sisters Este, Danielle and Alana Haim.
Per the pictures, the foursome has been having a good time in Hawaii, where they've gone to the beach, whale watching and hiking.
In addition to keeping hungry fans satisfied with updates from her whereabouts, Swift's posts have made headlines over the the showcasing of her famously covered belly button. The "Shake It Off" singer told Lucky magazine in 2014 she doesn't like exposing her navel.
"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," she said at the time. "I don't want people to know if I have one or not. 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."
