Wild Brawl breaks out at Hilary Duff concert in Los Angeles, on video

This isn’t what dreams are made of — a fight broke out at Hilary DuffLA’s “Lucky Me” tour stops at The Forum this week…and the glitter-filled incident is on video.

Watch the clip: A fan in a bright, shimmering crop top appears to have her hair pulled by another person in a black outfit as security tries to separate them.

It’s unclear exactly what led to the nasty fight – and bystanders are visibly shocked as they try to do everything they can to help defuse the ordeal. We guess that’s not what HD meant when she encouraged her fans to “take a crazy risk.”

It’s unclear exactly when the cat fight broke out – Hilary isn’t in frame, but there are musicians on stage, so it appears to happen during a song transition. You can see towards the end of the video that the stage goes dark and the lights take on a fiery color – perhaps for her performance of “Play with Fire.”

TMZ has reached out to the Forum and the LAPD for comment…so far, no response.

Otherwise, the concert apparently went off without a hitch: Hilary completed two concerts at the Forum on Wednesday and Thursday, which saw famous guests in the crowd. The actress and singer was supported by Mandy Moore, Meghan Trainor and even Demi Lovato … But no Ashley Tisdale following the viral moms group drama.

She is scheduled to take the stage Saturday night in Mountain View, California.
