Twenty five per cent of voters warmed to Auntie Pippa's love of style and baking and remarked on her closeness to sister Kate.
One respondent said: "I think Pippa makes a really fun auntie and I'm sure she'd be able to offer some solid advice to George when he grows up, as there is a lot of pressure that comes with being the future king."
In second place was reality TV star Kim Kardashian, auntie to Kourtney Kardashian's two children Mason and Penelope Disick, with 20 per cent of the vote.
Fashion designer Victoria Beckham came next on the list taking 15 per cent as auntie to sister Louise Adams' little girl.
One respondent said: "Victoria Beckham is definitely the best auntie in my eyes. Imagine how many fashion tips you'd pick up from her on a daily basis, and the shopping trips would be amazing."
Rihanna closely followed in fourth place, with 12 per cent of those questioned loving the singer's laid-back style.
The superstar has been posting photos of herself posing with her baby niece on Instagram.
Newlywed Cheryl Cole scooped fifth place with nine per cent of the vote, with many of the 520 respondents saying they would love to have the pop-star as an auntie to tell them all her beauty secrets.
Singer Beyonce Knowles was next on the list, with six per cent of the vote placing her in sixth place.
She has been there for Daniel Julez, little sister Solange's son, from the get-go and was even in the delivery room for his birth.
A spokesman for Wrappler, which commissioned the survey, said: "No one can deny that having a famous aunt would be amazing, and I think the respondents have it right when it comes to naming the best.
"I bet even Prince George gets bored of being a little prince every once in a while, and so I'm sure that having an un-royal auntie will be a great blessing when he grows up.
"As for the others, Kim Kardashian has been showing off her maternal side ever since North West was born, and I'm sure she'd make a great auntie to her sister Kourtney's two children.
"I bet they can't wait until they're grown up and she can show them the ropes when it comes to partying like a pro."
