It is Father's Day weekend and even though these fine fellas aren't dads yet, they sure are hot enough to be considered a zaddy.

Just take a good look through our gallery of celebrity zaddies to truly understand why these guys earned the title ... And while you're at it, see if you can guess the shirtless stud showing off in these hot shots.
