Emotional: Lady Gaga is reduced to tears by one of her biggest fans, ten-year-old Maria Aragon
She famously lives for her legions of followers, whom she calls her 'Little Monsters.'
And Lady Gaga proved just how much she adores her fans when she invited her biggest one onstage to join her for a duet in front of a 20,000 strong audience during her Toronto concert last night.
The singer, 24, invited ten-year-old YouTube sensation Maria Aragon to the gig after her cover of Gaga's latest single Born This Way went viral on the website.
Biggest fan: The singer welcomed the youngster on stage with a big hug
Gaga, real name Stefani Germanotta, welcomed the Winnipeg girl onstage at the Air Canada Canter to wild cheering from the audience.
The pair embraced, with an excited Gaga picking her fan up and twirling her around.
They sat down together at the piano, with Maria perched on Gaga's lap, to perform her toned-down version of Born This Way.
'I'm really excited that Maria is here today, because Maria represents what this song is all about,' Gaga told the audience.
Rising star: Maria, from Winnipeg, was confident in front of the 20,000-strong crowd
'It's all about the next generation and the future and no more divisiveness.'
Afterwards, the Grammy winner handed the microphone over to the confidant youngster, who thanked her idol.
Gaga's eyes filled with tears as she listened to Maria, a star in the making, as she gave a shout out to her family and friends back in Winnipeg and told the audience she'd be back to help perform the radio version of the single later in the concert.
'I just want to say I'm really grateful. I want to thank all of you for all your support,' Aragon said. 'I'm from Winnipeg and I came over here to sing for you, I hope you enjoyed it.'
Encore: Gaga invited Maria back onstage for a the radio version of the hit single
'If I could just touch one person, that's enough,' a tearful Gaga said after Maria had left the stage. 'She made me all nervous because she's such a superstar.'
Maria made international headlines last month when her tribute to the star, a video of her sitting at her keyboard playing Born This Way, received eight million hits in just five days.
To date, it has been viewed over 17.6 million times.
Miss Aragon was interviewed on television and radio after Gaga shared a link to the video with her eight million Twitter followers, writing: 'Can't stop crying watching this. This is why I make music. She is the future.'
Backstage pass: Gaga uploaded a photo of the pair after the show, writing 'Myself +10 year Old Lady Maria of Winnipeg. She signed my t-shirt, she ate my heart, just like you'
She even appeared on the Ellen show and Good Morning America last week.
The youngster displayed some fashion finesse for her debut performance, walking onstage in black sequinned trousers, a hot pink hoodie, black leather jacket and a white hat.
Her pièce de résistance was certainly a bright orange toy monkey, which she wore around her neck as an accessory.
Gaga, notorious for her wacky style, commented: 'The monkey is fabulous. Who styled you tonight?'
Sensation: Maria's YouTube video has received over 17.6 million hits to date
Maria told her that her sister was responsible for the ensemble.
She later joined Gaga and her backing dancer onstage for the uptempo, radio version encore of Born This Way.
Gaga uploaded a photo of the pair together backstage, each wearing a T-shirt bearing the other's image.
She wrote: 'Myself +10 year Old Lady Maria of Winnipeg. She signed my t-shirt, she ate my heart, just like you.'
Travelling in style: Gaga touched down in Toronto yesterday ahead of the concert and posed for pictures for famed photographer Terry Richardson on the runway
Maria appears to be taking her sudden stardom in her stride, answering reporters questions with poise as she left the arena.
She told journalists that she and Gaga had rehearsed for five minutes before the start of the concert.
Tonight Gaga will fly to buffalo for a performance before returning to Canada for a gig in Ottawa.
