The model-and-actress played secret agent Vanessa Kensington opposite the title character, portrayed by Mike Myers, in the hit 1997 comedy movie and one person still watching it is eight-year-old Damian.
She wrote on her twitter page: "My son's fave film is Austen Powers -he used to idolise Vanessa Kensington but has switched allegiance to the Fembots. (sic)"
Although she has a big fan in her house, Elizabeth - who lives on a farm in Gloucestershire, South West England, with Damian and her husband Arun Nayar - she is having trouble keeping her dogs happy.
The 45-year-old brunette beauty has several Labradors, but her favourite mutt Raja is unhappy with her because she has been away from home so much, while her pooch Emily is doing some strange things.
She revealed in other tweets: "Favourite lab Raja is cutting me dead. Obviously, I'm unforgiven for abandoning him all week. Wonder when the love fest will recommence?
"Wow ... my black lady lab Emily has started snorting and panting in her sleep. shocking noise. Hope it's a temp thing. (sic)"
