Britney Spears has seen the error of her ways – or so she tells her fans in a 342-word “Dear Fans” letter posted on her official web site. She doesn’t specifically mention her recent public disasters (the missing underwear, the tête-à-têtes with Paris Hilton, falling asleep in the middle of hosting a Las Vegas New Years’ bash), but she says she understands why her fans are disappointed in her. She promises to make it up to them with a new album and a new tour.
