Taylor Swift and Nelly got down atKarlie Kloss’s 24th birthday bash in the Hamptons on Saturday night.
Swift, 26, joined the rapper, 41, onstage in a black off-the-shoulder crop top and matching mini skirt with white sneakers for a duet to Nelly’s “Dilemma.” Swift took on Kelly Rowland’s parts of the song and the two sang and danced as the crowd cheered on in approval.
This isn’t the first time Swift and Nelly have collaborated. Last year, Nelly joined the pop star on her1989 stop in St. Louis, Missouri, and the two performed Nelly’s hit, “Hot in Herre” with Haim.
Kloss turned 24 last Wednesday, and Swift posted a selfie to commemorate her best friend’s big day.
