FILE - In this Oct. 1, 2011 photo, Rapper T.I. performs during the BET Hip Hop Awards in Atlanta. Rapper T.I. has joined country star Taylor Swift in a surprise duet at her concert in Atlanta. Toward the end of Swift's set on Sunday, Oct. 2, 2011, she introduced T.I. by singing the opening chorus of his hit song "Live Your Life." The packed house at Philips Arena screamed once he stepped onstage for the unannounced appearance and started to rap. (AP Photo/David Goldman) less
