Hailey and the singer make their joint red carpet debut at the prestigious celebrity event, fueling romance rumors. They post photos of each other on Instagram.
Hailey tells the Times UK that she and Shawn "hang out and he's super-lovely and a very, very nice young gentleman," adding, "But I am single."
She also says, "Justin and I were friends for a long time. I met him when I was really young and he was one of my best friends. Everybody knows that at a certain point in time that turned into something else, but that just happens when you're 18, 19. It was what it was. We went through a long period of time when we weren't friends. We didn't speak for quite some time and there was a lot of weirdness that went on. We've moved past that."
He tells E! News, "I am single. The Met Ball was such an incredible experience for me. It was just overwhelming in the most incredible way. I was so lucky for my first time going there to be able to go with someone like Hailey because she's such a vet and I really admire people like her because of how outgoing she is in such an overwhelming experience."

So committed to spending my life getting to know every single part of you loving you patiently and kindLY. I promise to lead our family with honor and integrity letting Jesus through his Holy Spirit guide us in everything we do and every decision we make," he shared with several photos.
