By night she's on stage as Posh Spice with the rest of the Girls, but by day Victoria Beckham fulfills her duties as reigning mistress of DVB jeans and mom to her three adorable boys. Yesterday she was in Boston for the stop on the Spice Girls tour, and she made a daytime solo appearance at the downtown Saks to pose on the red carpet in her denim and sign some autographs. A VB's work is never done, but at least she's recognized for her fabulousness. Victoria's Secret just awarded their twinsie named Victoria Beckham Sexiest Mom on their annual What Is Sexy? list. Well, I can name one proud husband who certainly seems to agree.
