Britney Spears and her sons shelter from wildfire at Four Seasons Hotel

Britney Spears and her two young sons have been forced to leave their home in Calabasas, California and move in to the nearby Four Seasons Hotel, in order to escape the threat of the fast-spreading Springs Fire.

The Mail reports that the fire has already burned through thousands of acres and destroyed as many as 25 buildings. Around 4,000 homes, including Britney's, are still threatened by the blaze, but a team of 1,000 firefighters are working hard to bring the fire under control.

Officials have reported that the fire seems to be weakening, and cool ocean breezes and possible rain forecast for today could help to improve conditions.

The fire, which started in Ventura County, has already covered about 10 miles.

Britney raced to her home on Friday afternoon to collect her sons, Jayden and Sean, before checking into the hotel, where she was later seen heading to the pool with her boys.

X17online reports that a number of celebrity homes are dangerously close to the wildfire. On Thursday, an eight-mile stretch of the Pacific Coast Highway was shut due to the approaching flames, and by Friday there were six separate fires, the largest of which was dubbed the Springs Fire.

Justin Bieber has a home near Britney, while the Malibu homes of Brad Pitt, Barbara Streisand and Steven Spielberg are also at risk.

Ventura County Fire Department spokesman Tom Kruschke said: "This is still a moving fire. If you were asked to evacuate, it will be a while before you are allowed in. And if at one point you are uncomfortable, please leave the area. It's not safe to stay."

BBC News reportst that extremely dry conditions and unpredictable winds have stoked the fire, which is moving towards the coastal resort of Malibu.
