Actress Joan Collins fled what she has called a "terrifying" fire in her Belgravia flat in London on Saturday night.

The BBC reports that the actress needed treatment for smoke inhalation and praised her "hero" husband, Percy Gibson.

She also praised Britain’s National Health Service and the London fire crews who rushed to her aid.

The London Fire Brigade said they were called to a seven-storey building on Eaton Place, Belgravia, at about 4:30pm on Saturday.

About 10 firefighters tackled the blaze which was brought under control an hour later.

In a tweet posted on Sunday, Collins thanked the NHS and ambulance service, as well as the Metropolitan Police for blocking off the street and the fire brigade for putting out the fire.

"And thanks also to the @NHSEnglandLDN #nhs #emt #Ambulance crew who took care of our smoke inhalation and comforted me. And the wonderful @metpoliceuk who kept the street closed and everyone safe. #gratitude." she wrote. 

In a separate tweet she said, "THANK U from the bottom of my ❤️ to the marvelous @LondonFire who attended to the terrifying fire yesterday in our flat. #threealarmfire My hero Percy had already doused the flames consuming the entire wall with handheld extinguisher (#donttakethisrisk). #gratitude #firefighters."

She also thanked her husband of 17 years Percy, who "doused the flames consuming the entire wall with handheld extinguisher."
