Catherine Rabett (sometimes known as Katie Rabett) (born 20 July 1960 in London) is a British actress. She played Cecily "Cissy" Meldrum in the BBC sitcom You Rang, M'Lord? (1988–1993). She very possibly achieved greater fame in the 1980s for the fact that she was a girlfriend of a prominent member of the British royal family, Prince Andrew, Duke of York, than for her acting. Rabett is married to the comic performer and scriptwriter Kit Hesketh-Harvey and they have two children.
