Fans think Abbey Clancy’s mum looks like she could be her sister

No way.

Abbey Clancy wished her mum a happy birthday with a sweet Instagram post today and it wasn't long before fans pointed out how similar mother and daughter are. So much so that many have said that they look like sisters with a number of people leaving comments on the post. Abbey's mum Karen Sullivan turns 58 this week and as you'll see from the photo below, she looks much younger and could probably pass for her daughter's sister. One Instagram user said:

"MUM ??? what ... wow so gorgeous".

Another commented:

"Holy shit that’s your MUM?"

While one other fan wrote:

"Looks like she could be your sister rather than your mum, absolute double of you".

As fans of the English-born model will know, she is married to Peter Crouch, a professional footballer who currently plays for Stoke City. They have three children, Sophia (6), Liberty (2) and their son Johnny was born in January of this year. The popular model won series 11 of Strictly Come Dancing with professional partner Aljaz Skorjanec and she has also presented Britain's Next Top Model.
