"He makes me feel like I've never felt before," Hilton, 28, tells PEOPLE. "Everything he does is romantic. He's amazing and we're really happy. He's beautiful, he's smart, he's well-educated and he treats me like a princess. We're just very much alike."
In turn, Reinhardt, 24, admits the pair has discussed a possible engagement. "When it happens, it happens," he says. "We've talked about it and we're having fun right now."
On Wednesday night, the duo, along with Hilton's mom and dad Kathy and Rick, and Reinhardt's mother Kelly Roberts, toasted Hilton's FiFi Award and then shared a family dinner together afterward.
Reflecting on their relationship, Reinhardt, wearing a Tom Ford suit Hilton picked out for him, says, "We just connected right from the beginning. We actually started hanging out on Christmas day – our families both go to Aspen every year. We met randomly on Christmas and have pretty much been inseparable. She's an amazing girl and a great businesswoman. She's the sweetest, most humble, hardworking girl. I'm very proud of her."
Hilton has called Reinhardt her sexy boy and Reinhardt enjoys that sense of humor. "She's always making me laugh," he says. "She doesn't take herself too seriously and it's a great thing to be a part of."
