Hurley, 49, plays Queen Helena in the show and although 12-year-old Damian has visited the the set of the drama, she admits it is too 'sexy' for him to tune in, reported Daily Mirror.
"This is an extreme, sexy adventure into royalty. It's quite out there. For me this is like sex, drugs and rock 'n roll at Windsor Castle. I don't want (Damian) to read the scripts and I certainly don't want him to watch it!," she said.
Hurley plays the queen in the show, she insists she is very different to the real Queen.
"There's little resemblance to Her Majesty Elizabeth II, Queen of England. But you never know. The beauty of this show is that we go behind closed doors."
