We met magician Collins Key backstage before his performance at Nassau Coliseum recently. He became known worldwide after appearing on the show "America's Got Talent."

He is such a great guy. We asked him if he had any hobbies besides doing magic? He joked, "No, I have no life. I like to play video games. I like Rubik's Cube and all that stuff. I love puzzles. I love mental games. I love reading."

We wanted to know how he was so lucky to be an opening act for Demi Lovato? Collins said, "I kind of crashed her set. I did some magic for her, and she liked the magic a lot. So she was like, 'You know, Collins, you should come on tour with me and open up'; and it was kind of a crazy move for her to do that, because a magician has never gone on tour before. She invited me on tour, and I got to go, and now I get to see Demi perform every night, and she's awesome."

After talking with him, he did some magic tricks just for us, and then we watched him perform at the Coliseum. He is amazing!
