Joan Rivers shows off cosmetic surgery as new play opens in London

As Joan Rivers new play, A Work in Progress by a Life in Progress, opens at the West End, attention has turned once again to the numerous cosmetic surgery procedures she has undergone in an effort to turn back the ageing process.

The 75-year-old comedian, famous for her brash New York accent and frank approach to plastic surgery, is said to have had two facelifts, one rhinoplasty and an eye tuck.

In addition, she's an avid user of Botox as a solution to rid her ageing appearance of any lines or wrinkles.

In the past, Rivers has stated: "You want to look as good as you can. We all want to look at attractive people. It's a business.

"My motto is 'better a new face coming out of an old car than an old face coming out of a new car'. Spend your money on you."

Joan Rivers: A Work in Progress by a Life in Progress debuted at the Edinburgh Festival Fringe in August this year.

The play is the comedian's first foray into theatre and is an autobiographical take on her life, set in a dressing room before the Oscar's ceremony. Rivers calls the production "a great evening in the theatre".

Though Rivers' candid approach to cosmetic surgery has blessed her with many fans and critics, she has been a leading advocate of the use of surgery to make ageing women look younger.

A recent survey published in the Medical Journal of Australia, for example, showed that demand for anti-ageing cosmetic procedures - like facelifts and eye bag removal - in the UK was higher than ever.
