VIDEO : Taylor Swift Performs ''See You Again'' With Wiz Khalifa on 1989 World Tour

Taylor Swift continued on her quest for world domination during her 1989 Tour Wednesday night. The 25-year-old singer added Wiz Khalifa to the already long list of stars who have joined her on the tour, bringing the rapper on stage during last night's Houston concert and fangirling just as much as the crowd over his presence. The duo performed Khalifa's current hit single "See You Again," the song in dedication to Paul Walker from the Furious 7 soundtrack.
