Singer/Actress Liza Minnelli is auctioning off thousands of items belonging to herself and mother, Judy Garland. The list includes Minnelli's famous Cabaret bowler hat and outfit, as well as her 1971 Rolls Royce Silver Shadow. Liza Minelli,71, won an Academy Award for her performance in Cabaret as Berlin nightclub singer Sally Bowles.

The auction will take place in Calabasas, CA, at a date to be announced in late May. Auctioneers are sorting Minnelli's collection to determine the auction prices.

It has also been reported that Minnelli is selling to simplify her life. "Throughout my long career, I have collected wonderful possessions and memorabilia…I want to simplify and share with my fans who have always been there for me," the actress said in a statement.

The Judy Garland memorabilia includes an MGM studio paycheck that was issued when she was 13 before she appeared in her first film, garments that Minnelli wore on stage, screen and in-person appearances, including a red sequined tuxedo from the 1970s, and a black-and-crimson beaded flapper dress.
