Big Brother fever hit The Harlequin shopping centre today as former housemate Gerry popped in to find out who Watford's shoppers are rooting for to win the reality show. Art gallery researcher Gerry, together with a Channel 4 film crew, wandered around the upper mall chatting casually with passers-by, as he helped film footage for Big Brother's Little Brother. Surrounded by teenage girls, Big Brother fans and the odd curious or confused shopper, the 31-year-old south Londoner, originally from Greece, talked enthusiastically with fans, signed autographs and posed for photos. Fans will find out on Friday night who has won this year's Big Brother.
