The ladies of Fifth Harmony and the guys of Los Angeles' KIIS FMÂ engaged in a competition of epic proportions when the girlsÂ stopped by the radio station.
It all started when the girls challenged the KIIS FM guys to a sumo wrestling match - in heels - "just so [they] know how it feels," in the words of Camila.
KIIS FM's response? Challenge accepted!
The sumo wrestling match evolved into a series of competitions, girls vs. guys, in arm wrestling, checkers, a dance-off, and a sing-off.
