Priory for Katona

Kerry Katona's gone back to rehab to get treated for depression.

She was admitted to the Priory last night.

She's previously been diagnosed with bi-polar disorder - it's when people suffer from more than one condition.

Filming on her MTV reality show, Crazy In Love, will continue when she comes out.

Her publicist Max Clifford says it's part of an ongoing battle for her.
