Victoria Beckham May 2011.jpgEven before welcoming a new addition to her family last month, Victoria Beckham has been keeping a relatively low profile over the past few months. Now, according to the Daily Mail, the Spice-Girl-turned-designer is set to make her comeback during New York Fashion Week on September 11.

Beckham is believed to be busy getting her body back into shape especially to coincide with the presentation of her Spring 2012 collection.

"Victoria has locked herself away at her Malibu holiday home where she has imposed a strict food regime," a source revealed. "She has instructed her chef to do a no-carb, no-sugar diet of just green vegetables and low-fat proteins.'

Victoria gave birth to a baby girl, Harper Seven, on July 10 in Los Angeles. The news was shared by hubby David via Facebook, where the couple have also shared photos of their new daughter.
