Outspoken rocker Morrissey has a new target in his sights - Catherine, Duchess of Cambridge's younger sister Pippa Middleton.

The former The Smiths frontman is a long-term animal rights campaigner and he has launched a savage attack on the sister-in-law of the U.K.'s Prince William over her love of hunting, branding her a "thickwit" and insisting she is "the sick face of modern Britain".

The Suedehead hitmaker was infuriated by photographs printed in a British tabloid last month (Oct13) showing Middleton posing with 50 dead birds at her feet following a pheasant shoot in Scotland.

In a statement, he writes, "On October 5, the Daily Mail newspaper gave us all an 'amusing' report of thickwit Pippa Middleton laughing as she stood over 50 birds shot dead by her friends and herself after a 'busy day's shooting'. We are reminded by the Daily Mail that Middleton is a 'socialite', which tells us that she is privileged and can more-or-less kill whatever she likes - and, therefore she does.

"The sick face of modern Britain, Pippa Middleton will kill deer, boar, birds - any animal struggling to live, or that gets in her socialite way. This is because her sister is, of course, Kate, who herself became 'royal' simply by answering the telephone at the right time..."

Middleton caught the world's attention with her figure-hugging frock at her sister's wedding to Britain's second-in-line to the throne in 2011.
