The infamous reality star, who first shot to fame by getting a boob job in the NHS, was arrested on Tuesday night in Yorkshire. She is expected to spend at least 24 hours in custody.
While the exact charges against Josie are unclear, it is thought her detainment is to do with both her outspoken social media posts and a complex personal relationship.
Mum of three Cunningham split from fiancé Andrew Goy earlier this year, this week posting a naked snap of her ex to Twitter.
With her former flame's dignity covered by only a small mushroom, Josie insulted the size of his manhood, as well as threatening to expose private texts he had sent her.
Josie's agent said it would be 'inappropriate to comment further' in the matter when approached for a statement.
UPDATE: Josie has since been spotted out and about, seemingly confirming rumours that she has now been released from police custody.
Cunningham first hit headlines when she had her A cup breasts boosted to 36DD - all paid for by the National Health Service.
She later provoked anger when she claimed she'd abort her unborn child in order to enter the Celebrity Big Brother house.
