Chaka Khan reveals her £1.75 secret to killing 'round the mouth wrinkles'

'Queen of Funk' Chaka Khan marked her 73rd birthday on Sunday...but the US singer, who's a great grandmother and enjoying the fifth decade of her career, looks significantly younger than her years. The Ain't Nobody singer - real name Yvette Marie Stevens - this week shared that she doesn't believe in cosmetic surgery and, unlike many of her showbiz peers, has never gone under the surgeon's knife in the name of cosmetic enhancement.
