Los Angeles (GN)Jessica Biel is spending Justin Timberlake‘s money! According to a new report, since marrying the singer, Biel has been shelling out $20,000 per week on designer shoes and bags from Bergdorf Goodman and Barneys NY. “She can’t resist anything from Chanel, Prada or Valentino,” a source said. Biel’s closet was so overstuffed, she had to rent a storage unit to house her new goodies! “Justin can afford it, but he’s still a little taken aback by how voraciously she’s spending.”
