It was reported by US Weekly that the former flames were pictured kissing one another a couple of times at Coachella over the weekend.
A source said: 'They were completely all over each other. They kissed a couple of times and Kylie and Kendall Jenner went over to their table for a bit as well.'
Fans have been wondering whether or not The Weeknd‘s new song Wasted Times is about him missing the model.
However, perhaps not much as he was reported to have been pictured looking cosy with another woman, the night after. The Canadian crooner, 28, and top model, 22, 'definitely looked like they were fully back together,' the festival insider told PEOPLE.
The Coachella source said the duo weren't going out of their way to hide their affections, explaining the pair 'were sitting on each other's laps and all over each other all night long.'
Also in attendance was Bella's newly single model sister Gigi Hadid but the beauty mostly kept to herself and 'wasn’t seen flirting with any guys.'
'She was there to support Kendall and Kylie and hang with her sister and their friends,' dished a source from the festival.
Bella and The Weeknd dated for over two years before splitting in November 2016.
The party helped kick of Kylie's new collection of makeup as well as Kendall's new Pizza Boys Radio show on Apple Music's Beats 1.
Though it seems like Bella and The Weeknd may be giving things another shot, it seems that the rapper wasn't reserving his attention for just her, however.
The star — whose given name is Abel Makkonen Tesfaye — was seen looking quite close with DJ/ex of Justin Bieber Chantel Jeffries on Saturday night at the festival.
The Wasted Times singer wrapped his arm around the 24-year-old social media favorite as they walked around the Empire Polo Fields together.
As things wound down later in the even, Chantel was spotted resting her head on The Weeknd's shoulder.
