What is the Priory, who are its celebrity guests, why did Katie Price check into the rehab centre and how much does it cost?
KATIE Price is currently spending 28 days in The Priory, where she'll get help following her drink and drug binges.
We take a look at the place that has helped stars such as Kate Moss, Lily Allen and Paul Gascoigne into sobriety.
What is the Priory?
The Priory, Roehampton, was built in 1811 as a private home and turned into a hospital in 1872. It is London's oldest private psychiatric hospital.
The Priory Group, which owns the famous Roehampton clinic, has 42 hospitals and teaching schools in the UK.
It also runs specialist centres for children with autism and other mental health issues.
Many celebrities have taken up residency in the hospital to treat gambling, sex, drugs, alcohol and computing addictions.
Celebrity guests at The Priory have included Ant McPartlin, Lily Allen, Paul Gascoigne, Kate Moss, Sinead O’Connor and Amy Winehouse.
Gail Porter famously slammed the clinic after being treated there in 2005.
She claimed she was compared to a car because her "engine wasn't working properly".
Why did Katie Price check into the rehab centre?
The former glamour model has checked into the £5,000-a-week rehab facility for 28 days.
Her family urged her to get help following drink and drug binges.
After a consultation at the clinic, she was diagnosed with co-morbid post-traumatic stress disorder (PTSD).
