How many calories are in hard liqour drinks?!

How many calories are in hard liqour drinks?

My boyfriend swears up and down theres no calories in hard alcohol. I think he's full of **** and want to prove it to him. So what kind of coloric intake is there in jack daniels, jose cuervo, captain morgan, and parrot bay (coconut) thats what we drink. I'm trying to go on a diet and he swears these drinks dont effect me as long as i drink them with diet coke and not regular. i say horse sh*t. what do you think?

also, if theres websites that prove how many calories are in each beverage, I'd like to see them so I can show them to him.

Thanks!
