Last night (October 7) was Beyoncé's final performance in the U.S. as part of her 2016 Formation World Tour.
Naturally, it was only right the singer went out with a bang, and was joined on stage by none other than Serena Williams.
Closing out her 49-date tour was made much easier by the star-studded array of special guests joining her throughout the performance, and seeing Beyoncé on stage with her good friend Serena feels just as natural, as it does surreal.
During a rendition of the hit single "Sorry," the iconic athlete came out to surprise the sold-out audience at the MetLife Stadium in New Jersey, and was sporting an amazing black sparkly leotard she very well could have borrowed from Bey's closet herself.
As Williams danced on stage alongside Bey, the crowd exploded with applause, making for one of the most memorable moments of the singer's impressive tour run.
It really doesn't get any better than seeing these two ladies singing the now-infamous lyrics "Middle fingers up, put them hands high / wave it in his face, tell him, boy bye" on a Friday night.
