If you happened to catch Taylor Swift's concert in Nashville on Saturday, Sept. 17, we have to admit that we are pretty jealous. On her Speak Now tour, Ms. Swift has been inviting tons of her famous musician friends onstage for duets, but she truly outdid herself at her second Nashville show when she brought out two of country's biggest stars -- Tim McGraw and Kenny Chesney.

In a video from the show, the crowd erupts into a roar as McGraw is revealed to be sitting next to Swift on a couch. Although McGraw is a seasoned veteran when it comes to performing, you can tell that he was delighted by the enthusiastic response from the crowd. Wearing all black and a cowboy hat to match, McGraw sang his track 'Just to See You Smile' along with Swift, who looked like a princess in her ball gown.

That same night, concert goers at the Bridgestone Arena went nuts as Swift introduced Kenny Chesney. It was truly pandemonium as Chesney took the stage, guitar in hand, to perform his single 'Big Star' with Swift. Both country stars rocked out to the tune, with Chesney holding true to his casual style as he strummed his guitar wearing a T-shirt, jeans, and a baseball hat.

During her show the previous night, Swift was accompanied onstage by Ronnie Dunn, and the duo sang his new solo single 'Bleed Red.' As if her concerts weren't exciting enough, these duets add an extra element of surprise to Swift's shows. We wonder who her next performance partner will be!
