Jenkins proves to be a typical prima donna

The Welsh soprano Katherine Jenkins has undoubtedly been advised to reveal her drug-taking past – cocaine, hash cookies, MDMA and ecstasy – to scupper the chances of anyone selling stories about her antics to the tabloids and harming her recent £6m deal with Warner Music.

In spite of her anodyne image relentlessly pushed by a high-powered PR team, I found La Jenkins a self-centred diva when we both appeared on ITV in Britain's Favourite View with Sir Trevor McDonald last year. Jenkins went everywhere backstage surrounded by a flotilla of helpers, endlessly re-spraying her hair and dabbing at her face until the last moment before she stepped in front of the cameras.

Luckily, the public chose the winning view of Wastwater in the Lake District, championed by the lovely Coronation Street actress Sally Whittaker, and Jenkins was completely upstaged.
