While performing with her girl group Fifth Harmony, the 23-year-old singer (Ally Brooke) was attacked on stage on Thursday (September 29) in Monterrey, Mexico.
In a video posted by TMZ, a male ran onto the stage and knocked her over during the concert. Security removed the man from the stage, and Ally was able to continue her performance with the rest of the girls.
Earlier this week, Ally was attacked when she arrived at an airport in Mexico by a man who was attempting to take a selfie with her.
After the incident at the airport, Ally took to Twitter to tell fans that she is safe and excited to continue performing.
