Zayn Malik Allegedly Punched Louis Tomlinson Leaving Him Concussed: Report

Sorry, One Direction fans … a reunion seems ever less likely to happen — because a new report claims Zayn Malik slugged Louis Tomlinson.

The Sun laid out the alleged altercation in an article posted late Friday … claiming the fight went down during the filming of a new Netflix reality show which was supposed to focus on the pair bonding on a road trip.

The outlet says sources told them the fight was triggered when Malik made a crack about Tomlinson’s mom … who died of cancer in 2016 — not the kind of quip friendships usually come back from.

Malik was allegedly wearing rings … and, he cut his former bandmate’s head — drawing blood and concussing Tomlinson.

The incident took place about 6 months ago … and, The Sun claims the two haven’t spoken since.

According to reports … Tomlinson has unfollowed Malik — the ultimate end to strained relationships in the modern age.

Star Magazine first reported the serious fight last year.
