One follower wrote: "She’s the image of you! Cool."
Are you sure that is not your double. Takes a double take. Your daughter is the spitting image of you. Well done Carol you must be very proud.

Carol and Katie appeared on The One Show last night (Monday June 24) presenting a segment celebrating the 50th anniversary of the moon landings.
Katie's father is Carol's ex-husband Patrick King. The pair also share a son, Cameron, who is now 22.
Carol turned heads recently when she joined Stephen Mulhern on ITV2's BGT spin-off show Britain's Got More Talent.
