Going shirtless, Orlando showed off his toned torso while singer Katy had her hair scraped back and sported a pair of beach shorts.
The lovebirds stepped out holding hands at the weekend as they hiked in Hawaii.
The couple, who were first spotted together in January were also seen dining out on the north shore of Kauai on Saturday.
The Lord of the Rings actor, 39, had joined Katy, 31, who was in town to play a private show at the Grand Wailea Resort in Maui on February 24.
One onlooker said: “They looked really loved up and into each other.”
The couple are reportedly looking to the future, with the Firework singer said to be keen to settle down and start a family with the Hollywood hunk.
Katy – who was previously married to Russell Brand for two years until 2012, and also dated John Mayer – was spotted with Orlando in the crowd at an Adele concert at the Wiltern in Los Angeles a few weeks ago.
The Roar star was spotted on the balcony of the intimate venue, which only holds 2,300 people, alongside Orlando and other stars including Jennifer Lawrence and Emma Stone.
