Kim Kardashian has figured out the best perk of dating Kanye West ... she gets to kick it with the one and only Beyonce.
While their respective men performed on stage, Kim and Beyonce were spotted hanging out enjoying Kanye and Jay-Z's concert in England this weekend.
An eyewitness at the show tells us the new besties "danced and sang all night together" and even made their way to the craziness of the mosh pit at the Birmingham stop of the Watch the Throne tour.
Should Kelly Rowland or Michelle Williams not be available, Beyonce may have just found Blue Ivy's newest babysitter.
