Shots fired! Bella Hadid just threw shade at Selena Gomez after the former Disney Channel star was caught kissing her ex The Weeknd.

The 20-year-old model is clearly not a fan of the rumored new relationship, and took to Instagram to mock Selena's sexy selfie, where she showed off her bare booty in a nude lace thong.

"Goodnight? love and light to you all..happy to be home," Bella wrote alongside the mini-video of herself posing in a mirror wearing a high-waisted black swimsuit.

Showing off side boob and her toned booty, the sister of Gigi Hadid was clearly taking a dig at Selena, who she unfollowed on the social media platform just hours before.

And we don't blame her. Just weeks after she split from the "Starboy" singer, Justin Bieber's ex was spotted making out with the singer in Santa Monica — completely breaking girl code.

Die-hard fans know Selena is BFFs with Taylor Swift, whose girl squad includes Bella's older sister Gigi.

However, Bella was not the only one who was not impressed with Selena's since-deleted selfie.

Fans were also quick to call the "Hands to Myself" singer a hypocrite for posing for the scandalous photo on photographer Mert Alas' account following her powerful speech at the American Music Awards, where she called out those who show off their bodies for attention.

"I had to stop, because I had everything and I was absolutely broken inside," she said on stage. "I kept it all together enough to where I would never let you down but I kept it too much together to where I let myself down."

She continued, "I don't want to see your bodies on Instagram. I want to see what's in here. I'm not trying to get validation, nor do I need any. All I can say from the bottom of my heart is I'm so grateful that I have the opportunity to be able to share what I love every single day with people who I love.''
