Watch: Beyonce and Taylor Swift Dance Together During Justin Timberlake and Jay Z’s Performance

A-List B-Day
Taylor Swift's 25th Birthday party was A-List: Beyonce, Selena Gomez, Justin Timberlake
Taylor Swift and Beyoncé joined forces again Sunday night at a Justin Timberlake concert – where they were spotted dancing together during Justin and Jay Z’s performance of “Holy Grail”!

The video is amazing; could these new BFF’s be any cuter?!

Justin was performing a sold-out concert at the Barclay’s center in Brooklyn, New York as part of his 20/20 World Tour, when he welcomed surprise guest Jay Z to the stage for “Holy Grail”.

A fan posted this video to Instagram during their performance, where Taylor can be seen rocking out with Queen Bey as they watched from the audience:

Justin posted this picture of him and Jay Z (the “King of Brooklyn”) later in the night:

Another fan posted this picture of Taylor Swift and Beyonce in the audience:

The pair (plus Justin and plus Jay) have been hanging out a lot this weekend, first at Billboard’s Women in Music luncheon, then later that night for Taylor’s 25th birthday party hosted at her Tribeca apartment.

Justin’s wife Jessica Biel (who is expecting the couple’s first child) also watched from the audience.

So, are Beyoncé and Taylor the best pop power BFF couple or what?
