Fifth Harmony star Ally Brooke Hernandez was knocked to the floor by a fan during a show on Thursday (29Sep16) night.
The girlband had been performing at the Auditorio Banamex in Monterrey, Mexico when the gig was interrupted by an overzealous stage invader.
Footage taken by an audience member shows a young man running up to her onstage to give her a hug.
He is chased by a security guard, who tries to pull the fan away, but the man grabs onto both of Ally’s arms and some of her hair. Once the guard manages to break the fan’s grip, Ally falls to the floor, before quickly standing up and resuming the song.
Ally has had an eventful week, as on Wednesday (28Sep16) she almost fell to the ground when a selfie-seeking fan approached her as she was walking through an airport in Mexico, before a security guard rushed to her aid.
Following the incident, the 23-year-old took to Instagram to post a message to assure followers she was fine and plead for them to act nicer towards others.
"Hi my loves, just to let you know, I am okay after the airport incident," she wrote. "Please be careful and gentle so nobody gets hurt. That was scary. Thank you!
"Monterrey, I couldn't be happier to be here! It's been a dream of mine since I was little. My favourite singer Selena Quintanilla had many beautiful performances here. And I get to perform in this city! I am beyond honored & proud."
She ended her post with crying face, praying hands, and love heart emojis and "Te amo", Spanish for "I love you".
