There's a reason why Taylor Swift anchors the highest-grossing tour of the summer: fans never know what they will get on a nightly basis.
On Sunday evening, meanwhile, fans were treated to yet another surprise: following her appearance at MTV's Video Music Awards, Nicki Minaj popped over the Taylor's concert in Los Angeles and joined the artist on a rendition of "Super Bass." The crowd went wild and Swift demonstrated her versatility once again. Seriously, she rules.
Selena Gomez has also been covering this Minaj track on the road. Check out a couple examples of her rapping like Nicki HERE.
