Bella split from the Starboy singer in November after an 18-month relationship, and he already appears to have moved on, after being spotted enjoying a romantic date night with Selena on Tuesday (Jan. 10).
The Victoria's Secret model may have unfollowed Selena on Instagram, but she still follows her ex. Meanwhile Bella remains among the 254 people Selena follows on the social media site.
Although Selena and Bella weren't believed to be close friends, they have been pictured hanging out together in the past with their mutual friends Immy and Suki Waterhouse. Selena is also a member of Taylor Swift's squad along with Bella's older sister Gigi Hadid.
The Can't Keep My Hands to Myself singer didn't appear to mind who spotted her during her PDA-filled date night with the rapper, whose real name is Abel Tesfaye, on Tuesday.
Selena draped her arms around the 26-year-old as they waited for their cars after dinner at Il Ristorante di Giorgio Baldi restaurant in Santa Monica, before engaging in some serious sidewalk PDA.
An insider told E! News, "They were there for three hours! Just the two of them. They came out and were so happy."
A second source said that while they initially wanted to keep their budding romance under wraps, they've decided they don't really care if everyone knows about them.
"[The Weeknd] always had a thing for Selena," a source told E! News. "He thinks she is extremely talented and sexy. They recently started talking before the holidays but she has been on his radar before."
They added: "They are on the same level with expectations and think the other is really fun. They are taking things slow and getting to know each other."
Earlier this month, former Disney star Selena, who famously dated Justin Bieber, reflected on her 2016 in Instagram's live video feature.
During the broadcast the starlet admitted that she was wants to focus on meaningful relationships. "I would say the biggest lesson that I've been learning since 2016 would definitely be awareness," Selena said. "I think it’s really important to be aware of like, the people that you're surrounding yourself with, the people that are purposefully the ones you are spending time with."
