(Cover) - EN Showbiz - Taylor Swift says being famous is just like being at school, apart from every excruciating moment happens at an awards show.

The country music star has been discussing the promo for her track The Story of Us, which follows a couple during their relationship. There is an embarrassing moment where Taylor sees her ex-boyfriend for the first time since their split, which was inspired by real events.

The 21-year-old knows people think being a celebrity would be fantastic and glamorous, but she insists it actually means anything awkward which happens is on a much bigger scale.

"Anytime I'm onstage or watching the music video, the first thing that comes into my mind is the person I wrote the song about. It's like the first thing that you think of is the moment that inspired the song, which is that excruciating, awful moment when you run into an ex for the first time," she told MTV News.

"[Being a star is] just like in high school, except [the awkward moments happen] at an awards show. You go on living a normal life, except on a different scale."

The Story of Us is also close to Taylor's heart for another reason. She shot the promo at Vanderbilt University in Nashville while tornados were battering the area. It made filming highly unusual as the whole cast and crew had to protect themselves from the difficult weather conditions.

"We had to hide. All of us, we had to hide in a room where there were no windows, so that was a little bit crazy. [But] other than that, it was incredibly fun," she explained.

The promo features all the people who play in Taylor's band, as well as her backing singer Liz Huett. Liz began working for Taylor after introducing herself at a meet-and-greet event, where she wowed the star with her voice. (C) Cover Media
