Carrie Underwood hits the stage with Rolling Stones in Toronto

She might be a country singer, but Carrie Underwood is also a huge Rolling Stones fan.

And while the audience was delighted to see her appear as a surprise guest during Saturday night's Rolling Stones concert in Toronto, Canada, no one was happier than the singer herself.

Carrie was ecstatic to be sharing the stage with Sir Mick Jagger and the legendary rockers and tweeted her excitement before she took to the stage.

-I.
