Surprise! Taylor Swift resurfaced after her summer-of-love getaway with beau Tom Hiddleston to perform at a birthday party in the Hamptons with Nelly on Saturday, August 6.

The “Shake It Off” singer, 26, and the “Hot in Herre” rapper, 41, joined forces for a fun-filled, flirty performance at Swift's BFF Karlie Kloss' joint birthday celebration with Mike Hess in East Hampton, New York.

A source tells Us Weekly, “Mike is friends with everyone. He is best friends with Josh Kushner, who dates Karlie. His parents own the Hess Corporation.”

At the star-studded event, Nelly performed his 2002 hit “Dilemma” with Swift, who sang original featured artist Kelly Rowland’s parts. “I love you, and I need you / Nelly, I love you,” she crooned to the Austin native MC, who rocked an all-white outfit.

Clad in a black crop top, black skirt and white sneakers, the blonde songstress strutted across the stage. At one point, she shook her butt before walking up to an unidentified man standing near the stage — not boyfriend Hiddleston, 35 — and giving him a quick kiss on the cheek.

This isn’t the first time the two musicians took the stage together. Nelly also joined Swift to sing “Hot in Herre” at the St. Louis stop of her 1989 World Tour in September 2015.

The “Bad Blood” singer has been noticeably quiet on social media following her ongoing “Famous” feud with Kim Kardashian and Kanye West last month. Amid the drama, Swift has been traveling the world with Hiddleston to places including England, Australia and Rome.
