Jay-Z Joins Justin Timberlake Onstage at Brooklyn Show, Taylor Swift and Beyoncé Dance in the Crowd [WATCH]

Justin Timberlake took over Brooklyn last night, Dec. 14, for a huge concert at the Barclays Center. Collaborator and rap great Jay-Z joined the singer onstage to perform his 2013 hit "Holy Grail." Taylor Swift and Beyoncé were hanging out in the crowd and, during the performance, the two were spotted singing and dancing together, MTV News notes. The concert capped off a special weekend for Swift, who celebrated her 25th birthday with a slew of famous artists.

Jay and Timberlake worked together on Magna Carta Holy Grail and The 20/20 Experience last year before taking their musical friendship on the road for all to see. Hova decided to give Timberlake the royal treatment while he was in New York, too. Check out the live collaboration below:

Bey and Swift were seated in a VIP section for the show, and during "Holy Grail" the pair were spotted dancing and having a great time.

Apparently the concert was not the only special event of the weekend. Swift shared some pictures from Saturday, Dec. 13, of her hanging with Jay, Bey, Timberlake, Sam Smith and the members of Haim. The best part of both pictures is Jay-Z's pose. Check it out.
