Taylor Swift is enjoying some fun in the sun while vacationing in Hawaii with her pals Este, Danielle and Alana Haim from the band Haim.
Swift showed off her bikini body in this group shot she posted on Instagram with the caption, "Greetings from Maui!" This is the first time the singer has shown off her belly button after telling Lucky magazine she like to keep that part of her body a mystery.
"She's always wearing, like, a 1950's bathing suit," Swift wrote on Instagram next to this pic of her in a polka-dot one-piece bathing suit.
Swift strikes a pose while out boating. "When we were whale watching and didn't see whales for 5 minutes and got all moody," she wrote.
The Haim sisters must be celebrating their Grammy nomination for Best New Artist.
"Hiking with the Squad in Hawaii," Swift captioned this low-key moment.
