'It's a dream come true!' Victoria Beckham tweets her delight as supermodel Gisele steps out in one of her dresses

She has already gone from Posh Spice to 'Frock Spice', with her critically acclaimed dress designs.

And Victoria Beckham was clearly thrilled to get the supermodel stamp of approval on her growing fashion career tonight.

Brazilian model Gisele Bundchen stepped out in New York wearing a chic black number from one of Victoria's collections - and Posh wasted no time in tweeting her delight at the news.

The supermodel wore the dress in New York's Harvard Club where she was being honoured for her environmental work at the Global Environment Citizen Awards.

She tweeted that she was looking forward to her forthcoming baby shower, which is being organised by Desperate Housewives star Eva Longoria and hairdresser Ken Paves.

'Very excited about my baby shower!' Victoria wrote. 'What do @Eva Longoria and @KenPaves have planned??? xvb'
