Happy 40th Birthday to Actress Jennifer Connelly!

Connelly is the definition of a true beauty. She has classic and striking features, never wears too much makeup (besides in one fantastic photo in the slideshow above), and her hair is always coifed and polished. We can't help but envy her consistent beauty whenever she steps out in the spotlight.

She has won Best Supporting Actress for her role in "A Beautiful Mind" (2011), and has starred in such blockbuster films as "Requiem For A Dream" and "Blood Diamond."
