Reports of six fans hyperventilating and passing-out from excitement came over the weekend when popstar Britney Spears unexpectedly joined Nicki Minaj on stage at The Factory nightclub in West Hollywood. According to an MTV.com report, attendees started crowd surfing to get to the stage. “Screams were so loud for Nicki and Brit you couldn't hear the music,” a source told MTV. “Bouncers couldn't hold the crowd back.” Britney’s surprise appearance at Nicki’s after-party came on the heels of the release of her remix, “Till The World Ends,” featuring Minaj and Ke$ha and it looks like the fans can't get enough of these two IRL. Nicki will also be touring with Britney this summer, after Enrique Iglesias backed out. So, what do you think: Are Brit and Nicki a match made in pop heaven?
