Fifth Harmony's Ally Brooke has been attacked for the second time this week.

The singer was on stage in Mexico when a crazed man ran up to her and started dragging her by the hair while she was performing.

Security quickly intervened and desperately tried to remove the man who was holding onto Ally's long hair.

The singer then fell to the ground and was clearly in shock, as her other bandmates rushed to her side.

However, she wasted no time bouncing back and within minutes resumed to entertaining the band's fans.

This came just two days after Ally sent a tweet out asking her fans to be more considerate after a woman jumped on her at the airport.

We hope she's OK.
