The couple — who dated secretly for months before their relationship became public last May — were photographed frolicking in the ocean together while on vacation in Turks and Caicos.
Swift wore a striped, retro-inspired two piece swimsuit for the outing and was seen cuddling up to her boyfriend in the water as they snorkeled and soaked up the sun.
“They were lovey-dovey,” a source tells PEOPLE.

Most of reputation‘s love songs — including “Gorgeous” and “Call It What You Want” appear to be inspired by Alwyn — and her latest single “Delicate” and the sexy song “Dress” also shed light on the start of their low-key relationship.
“Flashback to when you met me / Your buzz cut / And my hair bleached,” sings Swift on “Dress,” possibly referencing the haircut Alwyn sported while filming Billy Lynn’s Halftime Walk. The superstar had her hair bleached for a few months in the spring of 2016, and both stars attended the Met Gala that May.
“She seems to be in a great place both career and love wise,” a source recently told PEOPLE. “Joe is just an amazing boyfriend. He is very supportive. Taylor adores his family. She’s in a very good place.”
