The 25-year-old pop star put rumors to rest about her missing belly button by sharing some bikini photos in Hawaii with Haim sisters Este, Danielle and Alana.

Swift posted numerous photos from her sunny vacation in Hawaii on Friday (Jan. 23), including shots of her with posing with the Haim sisters on a large boat, fooling around on the beach, and hiking near a stream.

"Greetings from Maui! @haimtheband," Swift captioned in one of posts, which also included a brief clip of the crew spotting whales in the ocean.

Last last year, Swift told Lucky magazine that she\'s not a big fan of showing off her belly button.

"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," Swift said. "I don\'t want people to know if I have one or not ... I want that to be a mystery."
