Digital Spy's Celebrity Chart: January 18

Our favourite celebrities have been behaving most unexpectedly this week. One of the most pleasant, granny-friendly men on TV has admitted he's a binge drinker; a notoriously hard-living rockstar has given himself jogger's nipple after overdoing his marathon training; and a stunning model-turned-actress has revealed she hasn't always enjoyed fireworks in the bedroom. Nice to know they can still shock us, isn't it?
