In keeping with her trend of having at least one famous guest star at her concerts in big cities, Taylor Swift shared the stage with two of the biggest names in rap and R&B, T.I., and Usher, while in Atlanta, Ga. last weekend. Who knew the country-pop singer had it in her to hold her own with those two?! On Saturday, Oct. 1, Taylor, 21, shocked fans by singing Usher’s hit song, “Yeah,” with the original artist himself. We love how she wasn’t shy about sexy dancing with Usher and even taking over Ludacris‘s rap. The following night, Taylor started singing “Live Your Live” and was joined by T.I., who was just released from a half-way house after spending 11 months in prison. “Singing ‘Live Your Life’ with TI tonight was unreal,” Taylor tweeted after the show. “LOUDEST screams from the crowd, 14,000 people, hands in the air- welcome back @Tip!!” Watch both of the guest performances and tell us which one YOU prefer! Do you think Taylor’s Atlanta guest stars give her newfound street cred? via hollywoodlife
