What is you name?

Khloe knows her name since she was 18 months old.We put her in front of a mirror after her bath and she will go on:
-Khloe!
And then I say :yes and she will continue:
-Jensen!
-Yes.
-Bianka!
Now we ask her what is her name and her rapid answer is :
-I don't know!Khloe!
The bath ritual is the same:Khloe Jensen Bianka!
