Listen to One Direction on iHeartRadio

(Yahoo!) - Fun with friends turned into serious drama for Liam Payne.

The One Direction heartthrob was hosting pals in his London home when a fire broke out on the balcony of the 34th floor apartment on Monday night, omg! can confirm. Two men and a woman were injured in the blaze and treated for burns.

According to E! News, the fire – which was reported at 9:48 p.m. – stemmed from a young male guest's attempt to refuel an outdoor heater while Payne, 20, was inside in the kitchen. The singer raced out to help extinguish the flames and rode with his friend to the hospital.

A rep for the star had no comment about the incident or the medical status of the Payne's friend. However, omg! has learned Payne himself is OK, though likely shaken up.

The fire was a big one, according to a statement issued by the London Fire Brigade. Six fire engines responded to the scene and it took 35 firefighters 45 minutes to put out the blaze.

"Firefighters worked quickly and professionally to get the fire under control as quickly as possible," said spokesperson Laurie Kenny, who was on the scene. "Around 30 people left the building before we arrived and were not injured. Two of the occupants had superficial burns to their hands and the third had burns to his hands and face. All three have been taken to hospital."

The statement also noted there was "severe damage" to the balcony.

The cause of the fire is still under investigation, but Payne has been radio silent, not tweeting or otherwise commenting. However, he's probably very consumed with the health status of his friend.
