Justin Timberlake sings live at the opening show of his 20/20 Experience World Tour at Etihad Stadium on September 18, 2014 in Melbourne, Australia.

The latest addition to Taylor Swift's BFF posse just may be Beyonce.

At the Justin Timberlake show at Barclays in New York City over the weekend, Jay Z joined Timberlake onstage for "Holy Grail." And cheering along in the VIP section was Beyonce (duh) and Swift -- and fans were quick to capture the moment of the two together, however fleeting it might be.

In between songs, the two presumably talked about how silly Justin Timberlake lookedat Swift's 25th birthday party earlier that weekend.
