Bruce Willis fears he has developed a reputation as a cocaine user because he's always dashing to toilets to pee.

The star claims his age and the amount of water he drinks make frequent restroom trips necessary when he's out socially - and he worries that people are getting the wrong impression.

He tells Men's Journal magazine, "I drink far more water than I drink alcohol anymore. Whenever I'm in the company of someone who used to do this drug that makes you run off to the bathroom to do it, I'm reminded of how often I get up to pee now. I go, 'Oh, my God, I wonder if somebody thinks I'm doing blow in there'."
