It's been a few hours since Britney Spears was wheeled out of her house on a stretcher, possibly on drugs, after a dispute with Kevin Federline over custody of their children.

So what more do we know now? Well, the main news is that Britney Spears has gone to hospital for tests. Not maths or spelling tests - it's far too early to put a strain like that on someone as fragile as Britney Spears - but psychological tests. After a run of weird behaviour that's lasted long over a year, doctors will soon check Britney Spears' system for drugs and alcohol and then begin to assess her mentally to see if she's a danger to herself, her kids or anyone else around her. This process might take anything up to three days, which means by Monday morning we'll know if Britney Spears is a heartbreaking sufferer of a mental illness of just a bit of an overdramatic numpty.
