Victoria Beckham judges the final of Project Runway

Victoria Beckham got one step closer to being a catwalk queen - when she judged the final of Project Runway.

Celebrity pal Heidi Klum asked the Spice Girl to be a guest panelist on the season finale of her reality fashion design show.

Wearing an orange scoop-neck dress, the footballer's wife studiously took notes on the finalists' collections and told the winner he was "major".

Victoria, 33, joined Klum, Elle fashion director Nina Garcia and designer Michael Kors to judge the winner of Project Runway.

Super camp Christian Siriano was victorious in the US show, winning $100,000 from TRESemme to start his own clothing line, a 2008 Saturn Astra car, an editorial feature in Elle and the opportunity to sell his designs on Bluefly.com.

'Posh Spice' told the winner she loved his designs because they were similar to her own tastes. "I would be honoured to wear any of your clothes," she said.

"Victoria, great to meet you, we'll be in touch," Christian quipped back to his fashion idol.
