Earlier this year, the country star was also a surprise guest herself when she joined the Rolling Stones for a performance ahead of her set at Capital FM's Summertime Ball 2013.
Meanwhile, the singer is among the stars from the music world reacting to the news that Glee star Cory Monteith was found dead in his hotel room yesterday.
