Leigh Anne Pinnock was left in tears after she was reportedly slapped around the face by a crazed fan.

NOT OK.

According to The Sun, the Little Mix singer had an altercation while she was dining out with friends.

An onlooker told the paper: “He kept saying, ‘if my girlfriend was here, you would both feel really intimidated'.

“Leigh-Anne’s friend wasn’t going to let it go. She kept saying ‘no I wouldn’t, no I wouldn’t’. And Leigh-Anne started going, ‘Maybe I would, maybe I would’."

The man then told the singer’s friend to ‘shut up’ to which Leigh-Anne replied, "'Don’t say that to her’ or ‘don’t be rude.’"

The eyewitness added: "He walked around the table and leant into her and gave her a clean slap on the face.”

Leigh-Anne was understandably left stunned before breaking down into floods of tears as her friends comforted her.

The singer's representatives are yet to make a comment but we just hope Leigh is OK are this horrific ordeal.
