Beyoncé, Scarlett Johansson Make Top 10 Cleavage List

Launch Slideshow

Break out the push-up bras!

Today, Britain celebrates National Cleavage Day—but we think this is one celebration that those stateside can observe as well. In honor of the illustrious occasion, Wonderbra—the creator of the event, naturally—polled British women to come up with the top 10 cleavages (is that a word? It is now!) of all time.

British model and television presenter Holly Willoughby topped the list, but several of the U.S.’s biggest stars also made the cut. (We have just one question: Why on earth is Christina Hendricks not on this list?) Without further ado: check out our slideshow for the well-endowed winners!
