Firefighters were called to Hollywood actor Denzel Washington's Los Angeles home after reports of smoke coming from the building.
A representative for the star told the PA news agency there was no fire and "everyone is OK and safe".
Los Angeles Fire Department said it was called shortly after 8pm local time to a four-story mansion in the Beverly Crest neighbourhood.
No flames were discovered and firefighters were using thermal imaging cameras to find the source of the smoke, the service said.
The investigation was focused on one of several furnaces in the home that may have been recently serviced, they added.

Last month, Denzel's son John David Washington said that he had moved back in with his parents as the COVID-19 pandemic spread.
