Singing ace Taylor Swift shared the stage with rapper Nelly to make American fashion model Karlie Koss' birthday party a big bash.

The presence of Swift has come following her summer getaway with fiancé Tom Hiddleston. The duo performed on Nelly's classic masterpiece R&B jam "Dilemma." The birthday party was organized in the Hamptons on Aug. 6 at night.

Besides the rapper and singer, the party was also attended by Mike Hess who, according to a source, shares a bond of friendship "with everyone."  "He is best friends with Josh Kushner, who dates Karlie. His parents own the Hess Corporation," the source said while referring to Hess' presence as quoted by the US Magazine.

The 26-year-old "Shake It Off" singer and 41-year-old "Hot in Herre" rapper gave a flirty performance on stage on the 2002 hit, which fun-filled the whole ambiance.

The Nelly song that the duo performed was originally sung by Destiny's Child singer Kelly Rowland. The song hit the top position on the list of favorites in the USA and the UK. If the fans remember, the duo has not shared the stage for the first time. It was in September 2015 when the rapper joined Swift for "Hot in Herre" in Missouri. This was the time when she was on her 1989 World Tour.

NME reported that Swift has been seen appearing publicly a bit less after her online "Famous" feud with Kanye West and Kim Kardashian in July. She continued to travel the world with her beau to different places that included England, Rome and Australia while the online feud went on. In addition, singer Britney Spears, during a radio interview, also seemed to forget that she had met with Swift on two different occasions.

It was only last week when popular music artist Justin Bieber posted a screenshot of him FaceTiming with West and added a caption that read, "Taylor Swift what up."

The De Telegraaf features a video where you can watch the duo perform.
