Stalker Sarah, the 16-year-old girl who has taken over 4,500 photos with celebrities was on Good Morning America today to talk about her unique hobby. Frankly, Robin Roberts dropped the ball. We still don't know Sarah's last name, why her father has access to all of these celebrity events and why she's allowed to stay out so late on school nights. How is this girl still so elusive after being on a major network morning show!? However, Robin did get her photo taken with Sarah, so the morning anchor's fame has basically been cemented. Also, Sarah will be in New York City today, so if anyone sees her, please take a photo with her and send it to us!
