Ever since One Direction were formed, a portion of the fandom have developed an outrageous conspiracy theory. It suggests that Louis Tomlinson and Harry Styles are secretly in a relationship.
The theory is built on all numerous components. Every single comment either of the guys has made, and every slight hint in body language has been recorded, analysed, and used as "proof" of their relationship.
The portion of the fandom that believe in the relationship have called the pair "Larry Stylinson".
It was this theory that led to a whole other conspiracy theory – Babygate – which suggested that Louis's son Freddie doesn't actually exist, but was an elaborate scheme concocted to distract the world from Larry Stylinson.
