Today's celebrity cleavage features a funnywoman who's made us laugh countless times.

And, like the tomboy girl next door, we never knew how stunningly hot she was until she wore low-cut dresses and appeared nude in projects. This comedienne/actress is seriously one of the funniest gals around, but also happens to be incredibly attractive to boot. You wouldn't believe that she's 43 years of age!

Can you guess who it is?
