LMFAO's concert proved to be a little too hot for Honduras.

A fire broke out backstage during the group's December 28 show sending 15 fans to the hospital for smoke inhalation. Police think a "criminal hand" may be responsible for the blaze, according to local news source El Heraldo.

LMFAO's Redfoo tweeted, "Epic concert tonight! They told us that there was a fire when we were on stage. Then we went to the dressing rooms and there was smoke in the halls." He added, "Hope everybody is safe from the fire tonight! Love you Honduras!"
