Lingerie giant Wonderbra conducted a poll to celebrate National Cleavage Day held around the world today -- here are the celebrity cleavages that got the maximum votes!

Celebs and their bodies are always in the limelight, more so if they don't shy away from showing off their best assets.

So it's hardly surprising that all these sexy bombshells emerged the winners in a UK-based poll that Wonderbra conducted among 1,000 women to determine whose breasts are the best!

The Daily Mail reports that the bra firm unveiled a gallery of photographs -- the Cleavage Hall of Fame -- at its UK headquarters, showing the top ten in all their glory. All factors were taken into consideration, including the perkiness of one's breasts, how close they sit together and, of course, their size.

So who emerged the winner and who provided a competitive edge? Find out right here!

1. Holly Willoughby

The British TV presenter and mother-of-two, 30, made it to the top spot with her ample assets.

The stunning blonde actress, 27, came in at Number Two thanks to her fabulous curves.

In third place we have voluptuous songstress and new member of the yummy mummy club Bey, 31.

Rihanna comes up next with her youthful figure -- and the 24-year-old pop princess certainly dares to bare it all!

The late Hollywood actress' hourglass silhouette was legendary, so it's not surprising to find that she took fifth position.

Burlesque beauty Dita, 39, who recently launched her own line of lingerie has the curves to carry it off perfectly too!

Quirky Katy, 27, emerged a winner in the Wonderbra poll too -- many fans wish they were as well-endowed!

Another silver screen legend came in at eight -- the bold and beautiful Brigitte Bardot, now 77, had a look when she was younger that acquired iconic status.

The 31-year-old bootylicious reality star has made millions off of her assets -- and she's made the Celebrity Hall of Fame too!

And finally, rounding off the top 10 we have Dutch model Lara Stone, 28. Easy to see why she figures here!
