The pair have been snapped together twice over the last few days, and in pictures that you can see in the video above, show them looking rather loved up.
It turns out they have been on a romantic holiday to Hawaii after they were first spotted on a hike together last Saturday.
Katy and Orlando made no attempt to hide their relationship as they walked hand-in-hand in Nā Pali Coast State Park in Kauai.
They were then seen looking pretty smitten with one another, as they headed out on an evening walk the following evening.
Orlando was seen with a protective arm around the ‘Firework’ singer, with a massive grin on his face.
The couple were first linked at a Golden Globes after-party in January, when they were spotted flirting with one another.
"He would lean in to whisper into her ear and touch the small of her back as they chatted," a source told Us Weekly at the time.
Katy split from John Mayer last year, who she had been with on-and-off since her divorce from ex-husband Russell Brand in 2012.
