You can’t spell Tamsin Egerton without sin. The waif-thin British brunette has appeared on her native boob tube in a number of series that the hairy palms at Skin Central know nothing about because they don’t have any nudity. What we do know about is Keeping Mum (2005), a comedy starring Kristin Scott Thomas and funnyman Rowan Atkinson. But it’s Tamsin’s scene strolling topless in her home as a peeping tom spies her mouthfuls that is something Mr. Skin can’t keep mum about.
