As many Taylor Swift fans know, the songstress has been collaborating with some of her favorite artists while out on her Speak Now tour. Recently, while performing in Atlanta, Swift was joined onstage by rapper T.I. to perform a duet of his track 'Live Your Life.' Speaking with MTV, Swift recounted calling T.I. at the last minute to perform with her, and how starstruck she felt when she met him.

"Well, I called T.I. the night before the show, so I felt like it's such short notice that [he wouldn't do it with me], and he's just like, 'Hey, yeah, sure,' " Swift told MTV. "And it was just amazing. I was so excited 'cause I'm such a fan and I thought, 'This is such short notice, this is so ridiculous' that I'm asking him to do this the night before. And he's like, 'I'll be there.' And he showed up for sound check and we were all just so starstruck."

What's even more amazing about Taylor Swift's duet with T.I. -- aside from the obvious facts that she's a country-pop singer and he's a rapper -- is that their performance marked T.I.'s first since his release from prison on weapons charges. When T.I. stepped out on stage, it was not only a great experience for Swift, but also for the rapper himself since he was finally back performing for his fans.

Swift, who also has performed with rappers Nicki Minaj and B.o.B, also talked about how much she adores hip-hop. "I'm a huge hip-hop fan, and it's been so amazing to have so many incredible artists come out and to get to sing the hooks on their songs that I've been blasting in my car for the last couple years," Swift said. "It's been awesome. I couldn't have asked for more amazing special guests on this tour, and we're not finished yet."

Swift is still out on her Speak Now tour, with her next scheduled performance set for Oct. 20 in San Diego, Calif. We wonder what covers she'll perform or what artist she'll perform with while stationed in Southern Cali. Maybe Jason Mraz?
