Victoria Beckham is reportedly drinking wine to increase her appetite.The former Spice Girl - who is reported to have shrunk to a US size 0, a UK size 4 - is tired of people criticising her for being underweight and has turned to alcohol to "give her the munchies".A source told Closer magazine: "It's the reason she has a drink. If she has a wine or two then she'll have an appetite like everyone gets when they're on a night out and drinking. "She's got a big wine cooler in her house in Madrid and will have one in California when she finds a house. "She and David have a life director who is helping them organise the move and she is also sourcing nice Californian wines."It has been reported Victoria, 32, eats just one meal a day, refuses to touch carbohydrates and will only eat steamed fish, vegetables and salads.
