TORONTO - The day that 10-year-old Canadian singing sensation Maria Aragon has been anxiously awaiting is finally here.

The Winnipeg native is due to take the stage alongside her hero, Lady Gaga, at a sold-out show at the Air Canada Centre tonight.

Aragon's life has been turned upside down since a video she posted on YouTube last month was seen by Gaga, leading to millions of views and instant fame.

Gaga shared a link to the performance of her new single, "Born This Way," with her millions of Twitter followers, and the clip has now been viewed more than 17 million times.

The Winnipeg grade-schooler has been invited to join Gaga on her performance of the song at tonight's gig.

Aragon has already been interviewed on "Ellen," "Good Morning America" and "Access Hollywood."
