Taylor Swift and Sir Paul McCartney formed an unlikely duo on Sunday (15Feb15) as they jammed together at the Saturday Night Live 40th Anniversary Show afterparty in New York City.
The star-studded comedy show featured former SNL regulars Dan Aykroyd, Steve Martin, Eddie Murphy, Jimmy Fallon, Tina Fey and Will Ferrell performing in sketches alongside the likes of Justin Timberlake, Tom Hanks, Ed Norton, Jim Carrey, Emma Stone, Chris Rock, Melissa McCarthy, Alec Baldwin, Bradley Cooper, Kerry Washington, Swift and Betty White, with music provided by McCartney, Paul Simon, Miley Cyrus and Kanye West.
The whole group continued the celebrations after the broadcast of the three-and-a-half hour show on Sunday by heading to the Plaza Hotel to party.
Fallon took charge of the bash and kicked off the afterparty with Aykroyd reprising his Blues Brothers character with the funnyman, while McCartney and Swift sang and played guitar. The musicians then took center stage for a cover of Swift's pop hit Shake It Off, before performing a rendition of the Beatles' I Saw Her Standing There.
Fallon also recruited Michael Bolton, Cyrus and Ariana Grande for subsequent sets, with the Problem hitmaker teaming up with Blondie rocker Debbie Harry to sing back up for The Tonight Show host.
However, the biggest surprise came at the end of the night, when Prince made an unannounced appearance at the party, hitting the stage with comedienne and superfan Maya Rudolph, who had shown off her impression of Beyonce during the SNL 40 show.
Ironically, Beyonce herself was in attendance at the afterparty, alongside her husband Jay Z and actor Leonardo DiCaprio.
