Kate Middleton's mum and sister visit designer Alice Temperley

Kate Middleton‘s sister Pippa and her mother Carole have been snapped visiting Alice Temperley at her west London showroom.

They spent 3 hours holed up with the British designer last week, fuelling speculation that she’s making the bride-to-be’s wedding dress.

Kate, 29, is a big fan of Alice and wore one of her creations (pictured) for an official engagement with Prince William in Norfolk in December 2010.

With just weeks to go until the Royal Wedding, has the secret to her wedding dress designer finally been revealed?
