The 20-year-old model took to her Instagram account to upload a short video of herself baring her stunning curves in a swimsuit less than a day after photos emerged of her ex-boyfriend with the 'Heart Wants What It Wants' hitmaker.

Captioning the video, which has had nearly three million views at the time of writing, she shared: "goodnight ... love and light to you all..happy to be home (sic)"

It comes after Bella unfollowed Selena on Instagram when pictures of the rumoured couple outside Italian restaurant Giorgio Baldi in Santa Monica surfaced online.

A source said at the time: "At first, Selena and Abel wanted to keep their relationship a secret. But they've decided they really don't care if everyone knows about them."

Whilst another added: "Selena was focusing on getting herself back together and Abel was just getting out of a relationship, plus putting out his new album. Abel and Bella also were on and off towards the end of their relationship, so getting into something brand new was not what Abel was looking for."

And The Weeknd - real name Abel Tesfaye - is said to have had a crush on Selena for some time.

The source added: "Abel though always had a thing for Selena. He thinks she is extremely talented and sexy.

"They recently started talking before the holidays but she has been on his radar before. 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."

The news of Bella's unfollow will come as a shock to fans as the model previously insisted The Weeknd is still her "best friend" despite their split.

She shared recently: "There is no awkwardness. He is my best friend, and I am excited because I am walking during his performance."
