i actually love it. louis and zayn were in the same band, were together 24/7 for almost five years and then Poof! one day, they're relationship went down the drain. but perrie was zayn's fiancé and leigh-anne just knew zayn because of that. so of course she's gonna stick up for her best friend. but louis was best friends with zayn and i love how he's sticking up for zany's ex-fiancé instead of him.
