Taylor Swift surprised fans during her 1989 tour when she was joined on stage by Jason Derulo.
Swift was performing at the Nationals Park in Washington, D.C. on Tuesday night when she brought the Whatcha Say singer out.
They both performed Derulo’s summer jam, Want To Want Me, to the delight of the crowd.
And to even make it better, he surprised both Taylor and the crowd by taking off his shirt.
