Will.i.am EVACUATED After Hotel Catches Fire

"Black Eyed Peas" frontman Will.i.am was rushed out of the London Hilton on Park Lane moments ago ... after the 28-story building caught fire, engulfing the hotel in smoke. 


So far, no word on how the fire started ... and no immediate reports of injuries.

The London Hilton is EXTREMELY popular with the rich and famous ... as it's located very close to Hyde Park and Buckingham Palace.

Story developing.
