Toni Braxton - the female R&B singer you haven't seen, heard or thought about once in the last 12 years - has been hospitalised in Las Vegas.

Although the exact nature of Toni Braxton's illness hasn't been revealed, some have claimed that she was rushed to hospital with chest pains - a sign that Toni Braxton could be suffering from a flare up of her pre-existing pericarditis.

Pericarditis, of course, is an inflammation of the lining of the heart. Ironic, really, since Toni Braxton's most famous song was entitled Un-Break My Heart. When will these celebrities realise that singing lovelorn powerballads about diseases that they suffer from is no substitute for the progressive nature of medical science?
