It's pretty much a rite of passage these days when you're a famous female celebrity: Somebody's going to make a SEX DOLL that knocks off your image. MILEY CYRUS has one. It's called "Finally Miley" . . . and the box promises . . . (--Careful, Jedis) . . . quote, "3 achey love holes. "Not surprisingly, Miley doesn't take this as a compliment. The word is that she's considering a lawsuit. Meanwhile . . . and this makes me VERY sad for America . . . the company that makes the Finally Miley doll says the first batch sold out in less than 48 hours. I can't decide who sucks more? Miley or her blowup doll?
