Taylor Swift gave hometown fans a little something extra this weekend, peppering her two sold-out Nashville gigs with surprise guest appearances.

On Friday (Sept. 16), the pop-country princess shared the stage with friend Hayley Williams, frontwoman of the rock band Paramore. The two sang 'That's What You Get,' but that's not all Nashville got. Later, country star Ronnie Dunn joined Taylor for a rendition of his single 'Bleed Red.'

"Nashville, night one -- what a beautiful crowd!" Taylor tweeted after Friday's show. "And thank you to [Hayley] and Ronnie Dunn for coming out and singing/being awesome."

The following night, Taylor sang duets with up-and-coming popster Andy Grammer and country stars Tim McGraw and Kenny Chesney.

"Thank you Nashville for an unforgettable night," she tweeted. "That was crazy!"
