Singer Willa Ford, 20 dated Backstreet Boy Nick Carter, 21 for two years before breaking up last October. Now with her debut album "Willa Was Here", due in July, she's facing the wrath of Carter's fans-including everything from Web sites dissing her to signs saying "Die Willa." Still, "I can't let them stop me from doing what I've wanted to do since I was a kid." she says. Even if they aren't kidding around.
