At this stage in Taylor Swift's Speak Now tour, fans know to expect big-name local guest stars in each city. Last night (Nov. 18) in Columbia, S.C., the audience seemingly guessed the identity of Taylor's surprise collaborator before the country star could finish with his intro.

"He's one of the friendliest, coolest, most talented guys, and he comes from South Carolina," she said. "I hope it's alright with you if we have a guest tonight."

With that, she called to the stage Darius Rucker, who prior to becoming a country star was best known as the lead singer of laid-back '90s rockers Hootie & the Blowfish. Rucker descended a giant staircase and sang his 2009 hit 'Alright,' dueting with Taylor as the crowd went wild.

"Darius Rucker came out and sang with me tonight in South Carolina!" the CMA 2011 Entertainer of the Year wrote in a Twitter post after the show. "Such an amazing crowd! Hard to believe we only have 2 shows left."

Given that those final shows are in New York City, who do you think Taylor will play with next? Jay-Z, perhaps? Could T-Swizzy be in an 'Empire State of Mind?'
