Kate Middleton, formally known as the Duchess of Cambridge and her sister Pippa Middleton have been named the top beauty icons of 2011, by the UK Superdrug chain.
The sisters topped a list of celebrities in the poll, which was conducted with a pool of 3,000 women in the United Kingdom, according to the UK's Daily Mail.
The 29-year-old Duchess and her 28-year-old little sister have emerged as style icons over the past year, following the Royal Wedding in April.
Also landing in the poll's top five positions were former "X Factor" judge Cheryl Cole, Rihanna and British morning show host Holly Willoughby.
"What is fascinating is that four of the five celebrity women to appear in the top five are brunettes, which would indicate that while blondes may have more fun, brunettes are seen to be more beautiful," Superdrug Director of Beauty Sara Wolverson told the Daily Mail.
Beyonce, Emma Watson, Katy Perry, Victoria Beckham, Kelly Rowland, Lady Gaga, Adele, Angelina Jolie, Keira Knightley and Scarlett Johannson also made the list.
"We can see directly how changing celebrity trends affect our sales, from the 'Duchess effect' on sales of black eyeliner, to the 'Gaga effect' causing crazy nail art and our brightest cosmetics being a huge hit all year long, and Rihanna and Cheryl Cole's flirtation with vibrant red hair causing sales to rocket," Wolverson explained.
Prince William married Kate Middleton in London on April 29 in a ceremony watched by millions of people around the world, including more than 22 million viewers in the United States.
Meanwhile, it was reported that Pippa broke up with her boyfriend, former England cricketer Alex Loudon in November.
