Well, surprise, surprise.

Marilyn Monroe has been named the greatest blonde of all time in a new poll from Clairol Nice 'N Easy, Newslite reports.

Hey, nobody said it had to be a natural blonde.

The bombshell was joined in the top five by Grace Kelly, Brigitte Bardot, Cameron Diaz, and British TV presenter Holly Willoughby, according to the website dedicated to odd news.

"Marilyn Monroe has always been known for her iconic blonde hair," a Clairol spokesman told Newslite.

"But it's amazing to think that even now, almost half a century after her death, she has still beaten modern blondes to the top spot.

"Her hair is synonymous with 1950s glamour but it has stood the test of time against hair styles and colors which have come and gone over the years."

The poll of 3,000 people also reportedly singled out Scarlett Johansson, Stevie Nicks, Olivia Newton-John, Debbie Harry, Madonna, Doris Day, Goldie Hawn, Gwen Stefani, Charlize Theron, and Marilyn wannabe Paris Hilton in the top 20.

The study also found that Monroe was right -- gentlemen do prefer blondes. According to Clairol, men are more likely to make a pass at a blonde -- but go home with brunettes.
