UFC Vegas 121 weigh-in turned into chaos when Norma Dumont threw condoms and cash at Ailin Perez during their face-off. Perez did her signature twerk, then Dumont pulled condoms from her shorts and tossed them at her opponent, saying "You need this." While Perez picked them up, Dumont threw a wad of cash at her. Perez grabbed the money off the floor. The two fighters already had bad blood going into the bout.
