"Bella is furious Gigi might let Zayn back into her life," a source close to Bella revealed. "Bella knows the intimate details of their rocky past so she worries for her sister. Gigi shared all of her secrets with her sister, so Bella fears that if Gigi makes herself vulnerable to Zayn again, she could get really hurt or heartbroken. Bella wants to protect her sister from making the same mistakes again. There are good reasons Gigi and Zayn broke up in the first place so Bella is warning her sister to stay away from Zayn, he is bad news."
It's not surprising that Bella wouldn't want her sister getting back with Zayn, however... we do miss #Zigi.
