According to Kozlowski, theQueen turned to her grandkidsfor help learning to text (as grandparents do) and Harry would then sneak off with her personal cellphone and record a new (and hilarious) outgoing voicemail message.
In the book, Kozlowski writes:
"Prankster Prince Harry reportedly used the opportunity to record the following voice mail message on his grandmother's cell: 'Hey, wassup? This is Liz! Sorry I'm away from the throne. For a hotline to Philip, press one; for Charles, press two; for the corgis, press three.'"
What we wouldn't give to hear that audio with our own ears. Everything about the message is just *chef's kiss*.
