Most people (including us!) didn't know that Barbie has a surname - they realised when Barbie tweeted 'Happy National Siblings Day from the Roberts Sisters!'
She's even got a middle name!
We then received a call from taxi driver peter who told us even MORE about the Barbie clan...
Ken's full name is Kenneth Carson, he's got a mum called Edna and a brother called Tommy. Well, well.
Our minds are blown.
