The actress's daughter, Finty Williams, is all for the idea, reported Daily Telegraph.
"Finty's very keen on me having one. There's an Indian symbol that I like which supposedly represents life and love and everything. One of the cameramen who worked on The Second Best Exotic Marigold Hotel told me what it meant, but I'm a bit nervous in case I'm being set up. It might be unbelievably rude," Dench said.
Dench turned 80 in December but said the words 'old', and 'retire' are banned in her house.
