Rock offspring STELLA and MARY MCCARTNEY paid tribute to their beatle father SIR PAUL and late mother LINDA at the PETA (People for the Ethical Treatment of Animals) Humanitarian Awards in London on Wednesday (28JUN06). Fashion designer Stella, 35, and photographer Mary, 36 were honoured by the animal rights charity for their animal-friendly fashion and photography for PETA ad campaigns respectively at the star-studded bash in Stella's Mayfair store. Stella said, "This award is for my mum, in this shop which she never got to see. She'd be so happy. "The way we were brought up, it was always drummed into me to respect and look out for animals, as they don't have voices of their own." Mary added, "I'm unbelievably proud of everything that she (Linda) achieved. She would be so happy to know how much of an inspiration she was to everyone here." Linda died in 1998 following a battle with breast cancer.
