Deano put out the call for the coolest grandmother in Australia today and he found her, and her name is Christine!
Christine works as a receptionist at an escort agency and is so cool she agreed to record a rap song with Deano.
Listen to her rap above... Do you have a cooler grandmother than Christine?
N.B. the above photo is Betty White and not Christine.
