Footage by TMZ shows the couple with their arms wrapped around each other as they kiss while leaning against a railing overlooking the East River at Domino Park.
The two later headed to Manhattan’s Rockefeller Park where they engaged in another make-out session on a park bench.
The pair were seen in N.Y.C. earlier this week, when they left the pop star’s hotel and made a Starbucks run, waving at the paparazzi.
Bieber sported an oversized Tommy Hilfiger hoodie, Adidas sweats and sneakers for the outing, while Baldwin rocked a white tee under a tan jacket, denim cut-offs and white combat boots, as well as a band on her left ring finger.
“He is single and not dating anyone seriously,” a source told reporters on Wednesday (June 13).
“He is doing very well. He has known Hailey for years — she is very involved in Justin’s church. He likes hanging out with her. She is a wonderful person. They have fun together, but they are not in a relationship. They are two single people that enjoy each other’s company.”
However, another source revealed that it wasn’t that shocking to those who know the lovebirds.
“Hailey has always loved Justin and they have been best friends, so it’s no surprise that they’re hooking up again,” the source said.
Bieber and Baldwin dated previously from 2015 to 2016 before calling it quits on their relationship.
The “Sorry” crooner opened up about his relationship with Baldwin in a 2016 GQ interview.
“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,” he told the outlet.
“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,” he added.
After calling it quits, “we went through a long period of time when we weren’t friends,” Baldwin told U.K. newspaper The Times.
She continued, “We didn’t speak for quite some time and there was a lot of weirdness that went on,” adding, “we’ve moved past that.”
Bieber was last linked to on-again, off-again flame Selena Gomez. They began to rekindle their relationship in the fall after she broke up with The Weeknd, but they pumped the breaks on their reconciliation in March.
“Justin has no contact with Selena now,” added the source. “He seems fine with it.”
