Geri Halliwell finally tied the knot to her Formula One boss other half Christian Horner this weekend in a star studded ceremony. But there was one very special celebrity guest missing from the proceedings. Geri's fellow Spice Girl, Victoria Beckham. Sadly for the former band mates their 2 busy schedules didn't become 1 in time for the big day. Queen of fashion Victoria had a posh prior engagement at Singapore fashion week where she was showing her latest collection.
