The couple was photographed packing on some PDA at the San Ysidro Ranch in Santa Barbara on Sunday, looking more couple-y than ever.
An onlooker tells E! News they were spotted walking "hand in hand down the road" before they enjoyed some cocktails while sitting out on a grassy knoll. At one point, it appears Orlando decided to climb on top of Katy and go in for a passionate and steamy makeout session.
The super hot moment only puts a cherry on top of their blossoming romance.
In fact, sources recently told E! News they're definitely official.
"Katy likes how down to earth Orlando is," the insider explained to us earlier this month. "They seem to be getting serious and are an official couple. She calls him her boyfriend."
Of course this is only made even more obvious with the amount of time they've been spending together recently. Most recently, the couple returned from a short trip to London, arriving back in Los Angeles on March 13 with beaming smiles.
Shortly before that, they enjoyed a Hawaiian vacation filled with lots of outdoor activities, which they followed up with a few nights together in New York City.
One evening they hit up the Polo Bar in Manhattan and an on-looker tells us, "It looked like Katy was very comfortable being her self in front of Orlando...They were sitting close to each other, [and] Orlando was a gentleman."

Katy and Orlando were first rumored to be hooking up during the 2016 Golden Globes after getting cozy at a few parties together. They continued sparking romance rumors when they met up again at Stella McCartney's Autumn 2016 Presentation during fashion week followed by a fun night at Adele's concert in L.A.
The speculation turned into fact when E! News learned the "Roar" singer had taken a big step in being introduced to Orlando's son, Flynn.
"Katy has met Flynn, and they get along wonderful," another source told us in February. "She thinks he is so cute and such a well behaved kid! Katy would [also] like kids one day, and she is vocal about that."
Will Orlando end up being her future baby daddy? Guess we'll just have to wait and see how this romance pans out...
