Britney Spears has been taken from her Los Angeles home to hospital in an ambulance, police have confirmed.
She left her home at around 01:20 local time (09:20 GMT) and has been taken to UCLA Medical Center, according to TMZ.com.
It is believed she has been admitted to the hospital under a 5150 psychiatric hold, which means she poses a danger to herself and others.
Reports suggest the 26-year-old singer has been under the treatment of a psychiatrist who told Spears she was to be hospitalised last night and called local authorities.
It is thought the Toxic star's mental state has worsened in recent days, triggering the hospitalisation, which should see her held at the hospital for at least 72 hours.
Her mother Lynne and on-off boyfriend Adnan Ghalib are said to have travelled to the hospital in the same car.
No other details are available from the authorities at this time.
