Fashion guru Tim Gunn, a mentor on reality show Project Runway, has praised Victoria Beckham for being "articulate" and "thoughtful".

The Spice Girl, who will appear as a guest judge on the show's series finale, surprised Gunn with her in-depth knowledge of fashion.

Speaking to Metro, Gunn said: "I'd only seen pictures of her looking inscrutable. I'd never even seen an interview with her but I was blown away by how articulate she is about fashion.

"She really understands textiles, length, proportion and fit and she can talk about them all passionately. There was more depth there than I expected. She's a very thoughtful individual."

Beckham currently has her own denim clothing range called DVB.
