Her favorite food is seconds."—"I've never seen a six-month-old so desperately in need of a waxing," on North West, daughter of Kanye West and Kim Kardashian.—"I've had so much plastic surgery, when I die they will donate my body to Tupperware."—"Boy George is all England needs — another queen who can't dress."—"I blame my mother for my poor sex life.
