Fans are speculating on whether or not they're the new celeb couple to watch, when they were spotted hanging out together after the Met Gala yesterday.
Justin didn't attend the event, and Hailee walked the carpet solo (looking HOT BY THE WAY), but she met up with him after, and they got cosy on a couch.
TMZ are reporting that they have been officially seeing each other for a little over a month, and looking back at it now, there seems to be a few hints that we could have missed.
Justin was actually photographed inside a car Facetiming Hailee not too long ago.
When it's at Facetime level, it must be real.
The two apparently met after being reconnected by their mutual pastor from their church. Matchmaker pastor!
But could this get messy? Hailee is actually good friends with Selena Gomez, Justin's very famous ex-girlfriend. They have even been pictured together in the past.
We doubt it though, since Selena has been very public about her love for The Weeknd.
There's also the fact that Hailee supposedly already has a boyfriend, Cameron Smoller.
A source has even told GossipCop that the two are "just friends" and that the reports aren't true.
"Steinfeld and Bieber are friends, but they are absolutely not a couple. A mutual pal of ours and the actress exclusively tells us there's 'zero truth' to the claim Steinfeld and Bieber are dating," they said.
