Carol Vorderman and her daughter Katie King look more like sisters as they pose together to mark the 23-year-old’s graduation day.

Proud mum Carol, 54, took to social media to celebrate Katie’s graduation from Cambridge University with a masters in science.

Carol’s own mother and her son Cameron were also there to share in the special day.

The former Countdown star and mathematician graduated herself from Cambridge with a third-class degree in engineering.

Carol recently dyed her hair blonde and said she has had “a lot more offers of fun” since.

Here are some other celeb mums who could pass as their daughter’s sisters.
