The blonde heiress was seen out and about with her beau in Los Angeles on Thursday (5 September) and we couldn't help but notice how loved up they both looked. Aww!
Wearing a chic black and white dress with a black waist belt and black heels, Paris clung onto River's arm and smiled sweetly for the cameras.
The couple also couldn't keep their hands off each other as they made a pit-stop at a local restaurant and were pictured embracing at the till while they waited to be served.
Paris, 32, has been hard at work filming a music video this week to accompany her upcoming single 'Good Time', which will feature rapper Lil Wayne.
The blonde beauty inked a deal with Cash Money Records earlier this year and has wasted no time in getting stuck into her singing career after a seven year hiatus from music.
And it's no surprise that she appears to be bringing her signature style and over the top glamour to her visuals.
Paris kept her fans updated with sneak peeks from the set of 'Good Time' on Wednesday (4 September) and was seen wearing a couple of skimpy outfits with perfectly coiffed hair.
In one of the shots, Paris is stood in front of a table covered in dozens of blinged out necklaces and sporting a revealing one piece.She wrote: "Behind the Scenes of #GoodTime! #AccessoryTime"
Another picture sees the entrepreneur-turned-singer wearing a white caged bikini with gold detailing and matching white heels.
Paris is currently gearing up for New York Fashion Week and couldn't resist shopping for some new shoes while out with River yesterday.
And there is no rest of the wicked, as she is then jetting off to Milan. She tweeted about her packed schedule earlier today, writing: "Now time to pack for the rest of my trip. I first fly to New York then Milan then Bulgaria then Hong Kong then Singapore then home to LA!"
Does she ever stop?!
