Niall Horan was involved in car crash in London.

The One Direction star escaped uninjured after his Range Rover slid off the road and into a crash barrier upon skidding on a large patch of ice as he was being driven home from Heathrow Airport.

Eyewitnesses told The Sun newspaper that the 19-year-old 'Kiss You' singer climbed shakily out of the vehicle, in which he was a front seat-passenger.

The Irish heartthrob had just been picked up along with the rest of his bandmates, who were travelling in two other people carriers, from Heathrow's Terminal Five after arriving home from Japan on Sunday night.

One witness said: "They all waved as they went past, then the crash happened so suddenly. It must have been terrifying -- the car's wheels lifted off the road.

"We saw Niall climbing out. He looked shaken up but didn't seem hurt. He got into a people carrier and they drove off again."

A source close to Niall insisted he wasn't injured but was shocked by the sudden crash, saying: "The crash was a shock but thankfully he's fine."
