As an adult I have this problem when people ask who I work for. I completely understand how it makes you feel. One trick I've found is to say something like "I normally stutter when I say this but <name>". If you don't stutter, make a joke out of it and say you got lucky. If you do stutter you can also make a joke "See? Told you". I find this decreases the tension both for you and the people listening.
