AceShowbiz - Lady GaGa broke down in tears during a concert on Thursday, March 3 after performing an emotional rendition of her song "Born This Way" with a 10-year-old fan. The pop star last month invited Maria Aragon to join her on tour as she was so impressed with a YouTube clip of the little girl singing the track.

The "Poker Face" hitmaker kept her word when her tour touched down in Aragon's native Canada and called her young fan onstage during a show in Toronto on Thursday night. GaGa lifted Aragon onto her lap as she sat at a piano, and the two then performed a duet of "Born This Way", with GaGa visibly moved during the song.

After Aragon thanked the crowd and left the stage, Gaga could be seen weeping and taking time to compose herself before continuing the concert. She later took to her Twitter.com blog to post a picture of herself wearing a t-shirt with Aragon's face on as she stood next to the girl backstage.

Gaga writes, "Myself +10 year old Lady Maria of Winnipeg. She signed my t-shirt, she ate my heart, just like you." After the show, Aragon said, "Lady GaGa is really big and she's so amazing. Being supported how she was supported up there made me feel really great."
