Hailey Baldwin's on-and-off romance with Justin Bieber appears to be back on.

After attending the Met Gala earlier this week in New York City, Baldwin reunited with her ex-boyfriend at the Game Nightclub, where she was sporting a diamond ring on her engagement finger.

"They are said to have parted ways due to his grueling Purpose World Tour, but Hailey Baldwin and Justin Bieber found time to reunite on Wednesday as the pop star stayed in New York following his latest performance," the Daily Mail reported on Thursday. "The 19-year-old model was pictured meeting with Bieber, 22, at his after-party at Game Nightclub before heading back to her apartment with the Canadian crooner."

As the report also revealed, this isn't the first time Baldwin has sparked rumors of a possible engagement by wearing a ring on her engagement finger. Just last year, when rumors regarding her romance with Bieber first started swirling, Baldwin stepped out with a suspicious ring.

After spending time together inside of the Game Nightclub on Wednesday, Baldwin and Bieber were photographed getting into a black SUV, which drove them to Baldwin's apartment.

In February, Bieber spoke to GQ magazine, revealing he did not want to be in a committed relationship while on tour.

“I don’t want to put anyone in a position where they feel like I’m only theirs, only to be hurt in the end. Right now in my life, I don’t want to be held down by anything," he said. "I already have a lot that I have to commit to. A lot of responsibilities. I don’t want to feel like the girl I love is an added responsibility. 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. What if Hailey ends up being the girl I’m gonna marry, right? 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.”
