will.i.am had to be evacuated from his London hotel tonight (01.07.11) after a fire broke out.

The Black Eyed Peas star was among 1,500 people who had to leave the London Hilton hotel as billows of smoke poured out of its windows.

The 28-floor building in the city's Park Lane was engulfed after a fire broke out on the second floor earlier this evening.

At least 20 firefighters attended the scene to tackle the blaze, which began in the kitchen on the second floor.

The London fire Brigade later tweeted: "We believe the fire at the Park Lane Hilton is now out but are still checking the hotel's ducting just to make sure."

Will was staying in the hotel ahead of his group's performance at the London Barclaycard Wireless Festival tonight – and made it safely to the stage where he tweeted a picture of himself with bandmates Fergie and Taboo.

Earlier in the day, stars including Liza Minelli, rapper Tinie Tempah, singer Annie Lennox and rockers Status Quo had been in the hotel for the Nordoff Robbins Silver Clef charity awards.

London Metropolitan Police sources have said no one has been injured in the blaze and all the people staying at the hotel have been accounted for.
