The 28-year-old 'Just Dance' hitmaker, known by her wild hair and outfits, made an emotional speech during a show in Las Vegas, saying she is grateful to have an incredible fan support, reported The Daily Mirror.
"I want to say thank you to all of you, for inspiring me, for letting me be myself, it means so much to me," she said.
"I started go-go dancing when I was 18. The really, the most important thing I want to thank you for, is believing in just this tiny American girl from New York who had a dream," she added.
