Your and Zayn's parents are rich people...they being rich became friends..so you and Zayn were always everywhere together.You two never got along...Today you were at a party where he was also...something usual..

Zayn got jealous of a few people you were talking to because he wasn't the center of your attention even though he didn't want to show it...so he 'accidentally' pours some red wine on you*

"sorry babe it was an accident"

he called you that because he knows it annoys you
