A ROBBIE WILLIAMS fan stands the chance of winning GBP4,000 ($7,485) - if the ANGELS singer asks her out on a date. The British fan, 33, has placed a GBP40 ($72) bet with British bookmakers William Hill at 100/1 that she will step out with the former Take That star - and could even win GBP10,000 ($18,714) if she becomes his wife.
