While in Cannes at the Amfar Gala, Bella ran into her sister Gigi's ex-boyfriend, Joe Jonas.
If you remember their relationship, it was adorable and incredibly heartbreaking for Joe at the end.
Now, however, Joe is happily in love with his current gf Sophie Turner, as Gigi is with Zayn. So, when the two crossed paths, it was actually really sweet.
Bella gave Joe a friendly hug and kiss on the cheek. We mean, we doubt there'd be any drama while in front of all those cameras, but there's clearly no bad blood here.
We aren't sure the same would go down if, say, Gigi were to run into The Weeknd.
