Diva Thin Muffin Zappa (born July 30, 1979 in Los Angeles, California) is the youngest child of Frank Zappa and is the sister of Moon Unit Zappa, Dweezil Zappa and Ahmet Zappa. Diva once appeared on stage in 1993 at London's Marquee Club with the band "Z", featuring Ahmet and Dweezil Zappa. Her father, Frank Zappa, explained in a 1982 interview that Diva was so named because she was screaming louder than all the other babies in the hospital nursery. Diva Zappa founded 'Hand Made Beauty', a knitted and crocheted goods firm, in 2002.
