You better run, Selena! Gigi Hadid engaged in a fierce boxing session Monday — it might leave fans wondering if she’s getting ready to take on Gomez for hurting her sister Bella!

Last week, shocking pictures emerged of Selena laying kisses on The Weeknd, Bella’s ex-boyfriend. Despite having dated for two years, it looked like Gigi's sister was long forgotten by the “Starboy” singer.

After the pictures emerged of the pair kissing, Bella quickly unfollowed Selena on Instagram.

Gigi has shown in the past that she’s protective of her little sis. After the Victoria’s Secret Fashion Show in December, the supermodel was caught fighting with her sister’s ex at a club in Paris.

So it wouldn’t be surprising if Gigi chose to face Selena head on, too!
