"I'm in complete denial about being a celebrity. I spend 80 per cent of my time in my kitchen, and occasionally I'm wheeled out to pretend to be Kate Beckinsale for awards shows. I'm not at nightclubs every night, but I'll take my kid hiking, and several paparazzi will show up, and it's like, 'What? I'm not shaving my head in public. You need to leave me alone.'" Kate Beckinsale insists she's no BRITNEY SPEARS.
