Rocker Rod Stewart’s daughter Kimberly has made a tasteless joke about Sir Paul McCartney’s amputee wife, Heather oills, in an interview. The model is quoted as saying, “What has three legs and lives on a farm? Paul McCartney and his wife.” Heather devotes much of her time to charity work for other amputees after losing her leg in a tragic motorbike accident in 1993. This isn’t Kimberly’s first interview gaff: Jennifer Aniston was reportedly `devastated’ when Kimberly told a magazine, “I like her because she’s homely. She obviously has to have something else – it’s not like she’s gorgeous or anything.”
