Bust a move!

In honor of Friday being National Cleavage Day, Us Weekly is taking a moment to recognize Hollywood's hottest A-listers and their sexiest cleavage-baring moments.

Jennifer Love Hewitt has stolen the spotlight in the recent months by stepping out in sexy skin-tight dresses while flaunting her famous, and quotably favorite, assets.

"It's horrible to say, but I like my boobs," the 33-year-old Client List star told Maxim in an April interview. "They've always served me well. They're good."

Halle Berry is another star who, through the years, has gotten bolder with her style. At 45 years old, the ageless actress, who got engaged to her beau Olivier Martinez over the holidays, loves showing off her envy-worthy figure.
