Bieber and Baldwin were first romantically linked in 2014 -- with Baldwin claiming their relationship was platonic -- but a new round of rumors kicked off last month. In response, the "Sorry" singer revealed to GQ magazine that he "really love[s]" Baldwin, and now the 19-year-old model is also speaking out.
In an interview with E! News, Baldwin clarified the seriousness of her relationship with Bieber.
"We are not an exclusive couple," Baldwin said. "He's about to go on tour. Relationships at this age are already complicated, but I don't really like to talk about it because it's between me and him."
Bieber, 21, noted in his GQ interview that he wanted to make sure that he didn't want to repeat mistakes he'd made in previous relationships with Baldwin.
"I don't want to feel like the girl I love is an added responsibility," Bieber said. "I know that in the past I've hurt people and said things that I didn't mean to make them happy in the moment. So now I'm just more so looking at the future, making sure I'm not damaging them."
The Canadian-born singer even hinted at marriage. "What if Hailey ends up being the girl I'm gonna marry, right?" he said. "If I rush into anything, if I damage her, then it's always gonna be damaged. It's really hard to fix wounds like that. It's so hard… I just don’t want to hurt her."
Baldwin admitted she is "very open" on social media, but when it comes to relationships, she prefers to keep quiet.
"It really is my personal business," Baldwin said. "And I like to think my relationships are not between me the person and the whole entire world. It's hard. I don't think people are really able to understand if they're not in that position."
