Tensions ran high at the Barbie Cosplay Convention when Malibu Barbie threw shade at Fitness Barbie for wearing last season’s glitter boots.

One thing led to another, and suddenly it was blonde-on-blonde crime in the parking lot — extensions flying, spray tans sweating off, and at least three broken acrylics reported.

Witnesses say the fight started over who deserved to be Ken’s “main squeeze,” but honestly, Ken was last seen fleeing in a pink Jeep shouting, “I’m just a doll!”

Meanwhile, Grandma Barbie tried to intervene in her orthopedic Sketchers, but backed off once she realized she forgot her Life Alert.
