J-14 was the only mag at Miley's book signing today at a Barnes & Noble in NYC. With her mom, Tish, and little sis, Noah, in tow, Mi signed copies of her autobiography, Miles To Go, in stores NOW, for hundreds of waiting fans! You can even hear the fans cheer, "We want Miley!" in our exclusive video!

Miley couldn't have been sweeter to the people waiting in line -- she chatted with every single person and even took time to listen to their stories! And boy, does she have dedicated fans! One guy was even wearing a Miley-inspired airbrushed shirt and some people even gave her little gifts like stuffed teddy bears. Of course, we got that all on video for ya! Check it out (Psst! She even waved to J-14! Fast forward to 1:05!):
