Lady Gaga invited a 10-year-old YouTube sensation to perform with her onstage.

Maria Aragon's YouTube recording of Lady Gaga's new single, "Born This Way" garnered over 3 million views just two days after being uploaded! All these views soon brought the pint-sized Winnipeg native to the pop diva's attention when the Toronto-based radio station Virgin Radio brought the pair together for a phone conversation. "Not only do you have such a beautiful voice and you are so joyful to watch, but every once in a while, whether people believe it or not, I have a very bad day," she went on, "I was not having such a good day, and when [blogger Perez Hilton] sent me the video of you singing Born This Way, I was so overjoyed that I began to cry."

These kind words soon brought Maria to tears, and that was before the superstar proposed that the pair sing a duet over the phone! Gaga proceeded take it a step further by inviting the fifth-grader to perform at her concert in Toronto on March 3. A few days after her concert debut, Maria made an encore performance on the Ellen DeGeneres Show!
