Hailey Bieber says sex with a third person might sound exciting, but she believes a threesome with Justin, would destroy the trust they spent years building. “It’s funny because I feel like those ideas can be really fun and, like, sound really exciting.” “It doesn’t work for the two of us.” “Some people are in, like, open relationships and, like, it works for a time, but I feel like in the end it always doesn’t end up working.” “So I think the second you make the decision to do that, there is never going back from that.” “We worked very hard to, like, be in the space that we’re in now and, like, trusting each other and there’s, like, such a beautiful trust and bond that I just don’t think that’s something I would be comfortable with.” “I could ask him about any person, any past girl, anything and he’d be like, ‘Oh yeah, like this this this and this.’” “And I think that made me trust him a lot because I’m like, ‘There’s nothing I don’t know.’”
