Please suggest a website that gives the heights of
Entertainers.  if none available, please give us the
Heights of the following:

Bruce willis
Demi moore
Madonna
Alex baldwin
Mel gibson
Tommy lee jones
Brad pitt
Jack nicholson
Britney spears

Thank you.

Bruce Willis 6', Demi Moore 5'5",Madonna 5'4",Alec Baldwin 5'11",Mel Gibson 5'10", Tommy Lee Jones 6', Brad Pitt 5'11", Jack Nicholson 5'10", Britney Spears 5'4"

Your best bet is to go to IMDB.com. As far as I know, the heights of all those on your list are available there.

Willis always looks shorter, I guess because he's kind of stocky in his build, most references say 5-11 or 6 ft so there you go.
