The 38-year-old singer enjoyed a wild partying session at London’s Paper nightclub with 10 friends on Tuesday evening following the end of London Fashion Week, which saw her fork out a whopping sum for 10 bottles of Dom Perignon champagne, which were A A 500 each. The ‘The X Factor’ judge was in high spirits for the evening as she praised the club’s dancers as being “really inspirational” and complemented them on their raunchy PaperDolls ensembles.
