Chatting with PEOPLE while in Miami for Victoria's Secret PINK Spring Break Bash, the pop star, 18, admitted that although the twosome have been "on and off" in the past, he says they are currently "in a really good place."
Working together at the event, held at the Surfcomber in Miami, Simpson and the 19-year-old Hadid (one of the faces of the brand) were happy to finally be in the same town after the model was jetting around the globe for fashion weeks from New York to Paris.
"We didn't see each other for almost a month when I was overseas, so it was really exciting to see him again," she says.
Simpson, who performed at the event, explained how the twosome keep their relationship strong even while they're separated.
"It's give and take – you've got to have a certain trust", he says. "You build something, and for us it's been sustainable. [We're] very supportive of each other, she's stoked for me and it's mutual."
Hadid also took a moment to give an update on mom Yolanda Foster's health (the Real Housewives of Beverly Hills star has been suffering from Lyme Disease).
"She's battling a tough one, but she's helping a lot of people through her personal health journey," she says. "I think when she finally figures out how to help herself, she'll be able to help a lot of other people ... I'm very inspired."
