Jennifer Lopez has reputedly agreed to be Victoria Beckham’s “fashion guinea pig” for Posh’s dVb jeans collection. “Jennifer’s as fashion-obsessed as Posh and they’ve had several girlie chats about Victoria’s new range. Jen thinks Posh is incredibly stylish and has asked for some tips, but they’ve got different body shapes and she was concerned that things that look amazing on Posh wouldn’t suit her at all,” a source was reputedly quoted as saying. Following the Rock & Republic rumpus, Victoria Beckham is determined to make her dVb brand into a global success.
