(Cover) - EN Showbiz - Taylor Swift hopes the lighting guy "doesn't mess up" on tour now she's publicly praised him.

The American country pop singer is currently on the road with her Speak Now tour, and says the crew all work hard for long periods of time.

Taylor revealed that after the end of every worldwide series of shows she treats herself and all the crew to a big vacation, even if someone has done a "bad" job.

"Yeah actually, we usually take everybody on vacation. Like everybody. Every single person on the tour. That means band, dancers, crew. We usually pick somewhere beautiful and tropical, but we haven't started planning it yet, because the tour is only half way done. It's really wonderful to take everyone on a trip," she told the Kyle and Jackie O radio show.

"No, we don't do that," she laughed when asked if she excludes anyone for doing a bad job on tour. "Everyone's really good on this tour. Now watch me say that and have the lighting guy mess up tonight."

Taylor writes a different music lyric on her arm for every show. The 21-year-old star explained the words depend entirely on her mood that day.

"It's kind of like a mood ring. It's what I'm listening to at the moment, or what I'm feeling at the moment, or whatever lyric I'm relating to at the moment. They're all kind of based on my mood that day. And also, they have to be a lyric that I think is smart," she revealed.

"Oh it's never one of mine. It's always somebody else's. It's an artist I'm a fan of. There's been like 30, 40 so far, it's anybody from U2 to Dixie Chicks. It's like anybody. I have [written Eminem lyrics on my arm]." (C) Cover Media
