A lot of people aren't going to be happy about this...

Selena Gomez and The Weeknd were photographed making out and engaging in some heavy PDA after dinner at Giorgio Baldi in Santa Monica last night, and all signs point to them embarking on a new relationship.

"It’s new and nothing serious. It was a romantic dinner date in the rain. They acted like a couple. They ordered pasta and shared the food. She seemed very into him — she was smiling a lot. They left holding hands," a source dished to People.

The singer's ex Bella Hadid is going to be crushed! The former couple broke up late last year, but have been quite friendly in recent months and even hung out after the Victoria's Secret show in Paris in November.

The "Come & Get It" songstress clearly doesn't adhere to the girl code, because she's part of Taylor Swift's "squad," which also includes Bella's sister Gigi.

Bella should hook up with Justin Bieber just to give Selena a little taste of her own medicine!
