The Proposal star was stunned when his car was pulled over by ""creepy"" cops one morning - and he was asked to go to a hotel to complete a random urine test for drugs.

But the actor talked his way out of the test after admitting to police he is pee-shy.

Recalling the incident to America's late night talk show host Jay Leno, Reynolds explains: ""(I said), 'I'm happy to go down to the station', but I'm not going to a hotel with Officer Creepy standing behind me.""

But there was more to his refusal than Reynolds let on. He told to the officers: ""The real reason I can't go isn't just because it's beyond creepy - it's just I have maybe the world's shiest bladder. We would be standing there all day...

""I just can't perform like that.""
