Taylor Swift Performs Epic ‘Dilemma’ Duet With Nelly At A Birthday Party — Watch

Taylor Swift threw it back to 2002 when she helped Nelly perform his classic ‘Dilemma’ at Karlie Kloss and Mike Hess’ birthday party in the Hamptons! Click through to watch their epic duet!

Taylor Swift, 26, stood in for Kelly Rowland and sang her half of the 2002 masterpiece “Dilemma” when Nelly called her up onstage during an August 6 birthday party. Taylor and Nelly were both in the Hamptons for a joint birthday party for their pals Mike Hess, 30, and Karlie Kloss, 24; what better way to celebrate than by convincing Taylor to jump in on one of his biggest hits!

Apparently, Taylor was a little reluctant to get up onstage, but with some coaxing, Nelly got her to bust out the duet. And of course she knew every word to Kelly’s half of “Dilemma,” duh! She probably sings it in the shower, just like the rest of us! She looked like she was having an absolute blast in footage taken of the performance, singing to Nelly and strutting her stuff on the stage.

Her outfit was super cute too! We love the combo of the white sneakers with a sexy crop top and mini skirt, especially because she’s started dressing so prim and proper again now that she’s been dating boyfriend Tom Hiddleston, 35! It’s nice to see that Taylor’s having fun even though she’s having to deal with Tom being all the way back in Australia!

Taylor has been missing Tom so much since they had to (temporarily) do the long distance thing, that she’s feeling like it’s a “shock to her system,” a source told HollywoodLife.com EXCLUSIVELY. Taylor and Tom aren’t going to be able to see each other until the end of August, when he has a break from filming Thor: Ragnarok, but she’s just so lovesick she may not be able to wait! In the meantime, she’s got early aughts jams and birthday parties to keep her mind off things!
