Rapper T.I. --  just days after being released from an Atlanta halfway house  --  made his return to the stage Sunday night by performing a surprise duet with country music sweetheart Taylor Swift.

The unlikely duet took place when, towards the end of Swift’s show in Atlanta, she began singing Live Your Life, which T.I. originally recorded with Rihanna. Much to the delight of the audience, T.I. joined her after making a grand entrance down a staircase in the middle of the stage.
