She dared to go bra-less in the powder blue gown, which left little if anything to the imagination. The brunette beauty certainly stole the spotlight from her fellow models, including bestie Kendall Jenner, and was getting major attention from rappers A$AP Ferg and A$AP Rocky at the party — which might have been part of a plan to make her ex-boyfriend, The Weeknd, jealous.

The “Starboy” singer was recently spotted hooking up with fellow pop star Selena Gomez just two months after their breakup. Even though she has yet to speak out about her ex’s rumored relationship, Bella did throw some subtle shade when she posted a sexy selfie to rival Selena's.
