NICOLE Kidman and Rebecca Gibney have topped a list of the 10 most influential celebrity mothers in Australia in a survey of more than 2000 people.

The study was carried out by brand, media and communications researchers Millward Brown, who measure how well celebrities are liked and how much they are talked about online and offline.

An overall “Cebra” score is produced, indicating to the celebrity’s attractiveness to marketers.

“This is a list of mothers who could most influence buyer-behaviour,” company account director Hannah McHard, said.

“Nicole Kidman tops the list because she is seen as clever and sensible; she has been through a lot and her strength of character is something that many mothers would identify with.”

Nicole, who has two children to husband Keith Urban, was the highest ranking mum in the index, but with a Cebra score of 65% she only just pipped Rebecca Gibney and Olivia Newton John (both 63%) to the top position.

1) Nicole Kidman

4) Dannii Minogue
5) Elle MacPherson
6) Kerri Anne Kennerly
