Bella Hadid puts on a brave face as she steps out in New York amid claims she feels 'betrayed by pal Selena Gomez dating her ex The Weeknd'

She's kept a relatively low-profile since her friend and ex-boyfriend went public with their romance earlier this week.

But it seems that Bella Hadid has been left smarting over Selena Gomez's new romance with The Weeknd.

According to TMZ, the 20-year-old model has been left feeling 'betrayed' and 'backstabbed' by the singer, 24, who went public with the rapper earlier on this week.

The rising supermodel is said to have been left feeling betrayed by Selena's actions - especially given the Kill 'Em With Kindness singer is her elder sister's best friend.

The catwalk star is said to have been the one who pulled the plug on the romance two months ago, as a 'bi-coastal relationship was too difficult'. 

But despite finishing the relationship, the website reports that insiders in the model's camp say 'she feels betrayed because her ex and Selena hooked up almost immediately after Bella and Weeknd ended their relationship'.

Allegedly having only found out about the realtionship via the Internet, Bella was left fuming and even went as far as to unfollow Selena on Instagram - prompting claims their friendship is done for good.

MailOnline has contacted representatives of Selena and Bella for comment. 

Despite apparently being wounded by the latest twist in her romantic life, Bella ensured that she didn't show any emotional heartache when she stepped out in New York.

Cutting a cool and collected figure as she stepped out in the city, the Balmain pin-up flashed a glimpse of her toned torso as she strode out in a clingy white graphic print top, jean vest, and sweatshirt.

'Selena was focusing on getting herself back together and Abel was just getting out of a relationship, plus putting out his new album,' a source told E! News.

'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.'

The insider added: 'Abel though always had a thing for Selena. He thinks she is extremely talented and sexy....... They are taking things slow and getting to know each other.'
