For 72 hours, T.I. celebrated the end of his 11-month prison bid with a slew of homecoming appearances at high-profile events. After hitting the stage with Young Jeezy at the BET Hip-Hop Awards, the rapper made a surprised appearance at Taylor Swift's concert in Atlanta.

Near the end of the country songbird's Sunday night (Oct. 2) show at the Philips Arena, she introduced the Rubberband Man while singing Rihanna's chorus on his chart-topping hit 'Live Your Life.' T.I. stepped onstage in front of screaming fans as the two Grammy winners stood side-by-side performing the anthemic song.

Swift has become quite the ambassador for hip-hop on her U.S. tour. On the previous night, the singer brought out Usher for a rendition of his 2004 single 'Yeah.' Even more surprising was Swift's rapping skills as she started spitting Ludacris' verses from the song. The other day, Nicki Minaj jumped onstage with Swift to perform 'Super Bass' at her concert in Los Angeles.

Meanwhile, back at Swift's show in Atlanta, rappers T.I., Nelly and Young Jeezy were photographed hanging out backstage. Who knew they were Taylor Swift fans? “Singing ‘Live Your Life’ with TI tonight was unreal," Swift tweeted after her sold-out concert. "LOUDEST screams from the crowd, 14,000 people, hands in the air- welcome back @Tip!!”

Indeed, welcome back T.I. You are certainly living the life.
