Inspired my a chat with my DSis I would love to know the celebrity names you got wrong for years and then found out the actual name!
So far we have:
Me - I though John Torode was Jonty Rhodes until about 2 years ago
DSis- until today though Xabi Alonsi was called Chappy
DSis again - (this is my favourite) thought Benoit from bake off the professionals was called Ben and they had given him a nickname of BENwaaaaa a'la gavin and Stacey.
Please tell us we are not the only ones
