Hosted by MC Jimmy Fallon, the roaring shindig, held at New York's Plaza Hotel, delighted attendees with a plethora of kickass performances!
The night started off with a Blues Brothers performance featuring Taylor Swift, Paul McCartney, and Dan Aykroyd.
According to an insider:
"Taylor was dancing and blowing kisses to the girls from HAIM."
TayTay and the Beatles frontman even did their own rendition of the 25-year-old's hit Shake It Off!
Other A-listers who reportedly performed include Miley Cyrus, Debbie Harry, and Ariana Grande who stunned the audience with her rendition of Respect by Aretha Franklin!
To top off the night, Prince took the stage and was joined by SNL's own Maya Rudolph!
The source gushed:
"Maya was clearly a huge Prince fan and sang back-up…[She knew] every word to the song."
The party — which also included guests such as Emma Stone, Leonardo DiCaprio, Beyoncé, and Jay Z — went til 4 a.m.!
We just hope no one is too hungover!
Ch-ch-check out some of the performance (above)!
