Justin Bieber and Hailee Stenfield are now an item.

The two pop stars have been dating for over a month after getting introduced by a mutual church pastor, TMZ reported.

Bieber was photographed last month in the middle of a FaceTime video call with the 20-year-old Steinfeld.

They didn't attend the Met Gala together — Steinfeld went alone — but they met up afterward in New York City last night, according to the celebrity gossip site.

Their growing romance is noteworthy considering Bieber's longtime on-again, off-again girlfriend Selena Gomez is in the same group of friends as Steinfeld - a squad that also includes Taylor Swift.

Both Gomez and Steinfeld appeared in Swift's "Bad Blood" music video together.

Steinfeld admitted last year, however, that the Swift-led girl squad isn't as close as their fans may suspect.

"I think people think we spend a lot more time together than we actually do," she told Seventeen magazine last August.

That group of friends faced a situation recently when Gomez began dating singer The Weeknd, who previously dated Bella Hadid, the sister of Swift's good friend Gigi.

It's also becoming clear that Bieber, 23, has a thing for girls named Hailee's. 

He dated model Hailey Baldwin for a few months at the beginning of 2016.

In addition to her singing career, Steinfeld is an actress who has appeared in movies such as “Pitch Perfect 2.”
