Liza Minnelli is two inches shorter because of hip surgery.

The 66-year-old star - who has had various medical problems - has revealed she has shrunk in height after having an operation to replace her damaged hip.

Speaking to the New York Post newspaper to promote the 40th anniversary Blu-ray DVD release of her iconic film 'Cabaret', Liza said: ''The colour's more vibrant, the experience is heightened, glitches were fixed, stuff's been added and, frankly, I don't know what the hell Blu-ray is! I know I was 5ft -5in then. From hip surgery I'm 5ft 3in now.''

The singer-and-actress - who won the Best Actress Oscar in 1972 for her performance in the musical movie - also revealed she has kept all of her costumes from 'Cabaret' and she treasures the mementos.

She added: ''I've managed to preserve my old costumes. Like all those Halstons. I once saw an architect store his plans in very thin drawers. Since hanging jerseys or heavy beaded things stretch, I now store all my outfits in thin wooden drawers.''
