Bella Hadid and The Weeknd's relationship status has fans in a constant state of anxiety ... and that seems to be intensifying after the "Starboy" singer was caught leaving Hadid's apartment on Tuesday night. 

The Weeknd, whose real name is Abel Tesfaye, has been "hanging out" with the half-Palestinian model just weeks after splitting with Selena Gomez. 

"Bella and Abel have been in contact since Abel and Selena split, but they are not back together," a source told E! Online.

 "Abel reached out to Bella asking to hang out and catch up, and she decided to see him and see where things go. She knows that if they don't date again, they can at least be good friends."

Hadid and Tesfaye previously dated from April 2015 to November 2016. After their breakup, the Canadian singer began dating Selena Gomez, a relationship that ended earlier this month. 

Gomez was seen with her ex, Justin Bieber, and Tesfaye with Hadid ... and the internet is losing it. 

Hadid and The Weeknd: "The latest episode of date your ex"

BREAKING: The world is back to normal

"The comeback of exes"

Others are disappointed in Hadid ... and launched a hashtag titled: #PrayForBella

But, most people were a bit too excited

"My heart's soaring"

Is love complicated? Or is ABELLA complicating things?

Of course, some resorted to jokes

"ABELLA is back!" it seems

"Did he and Selena just pretend to be in love for months to piss off their exes?"

Current situation in a nutshell

True or untrue ... that is the question
