The Welsh singer told Esquire that she has met the monarch several times and feels "really sorry for her".
Church explained: "I've met her about seven times and she never remembers me. When you get close to her you realise she's an old woman and has no idea what's going on.
"I feel really sorry for her. She probably doesn't want to be wheeled out at every Royal Variety Performance to watch scantily clad dancers and s**tty comedians."
The 24-year-old performer also told the magazine that she never gets chatted up by men.
