The Poker Face hitmaker kept her word when her tour touched down in Maria Aragon's native Canada and called her young fan onstage during a show in Toronto on Thursday night.

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

Lady 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, Maria 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."
