The `Breakaway` hitmaker insists she would feel like a "tool" if she called a venue to make a booking for herself but is happy to have her assistant arrange things for her.
She said: "I do love it when you call a restaurant and they`re booked, then you have an assistant call, dropping your name, and somehow a table is found.
"I`ve never dropped it myself though, I`d feel like a tool."
However, Kelly - who shot to fame after winning TV talent show `American Idol` in 2002 - insists she never goes out of her way to be noticed by anyone and can`t understand why some celebrities enjoy being spotted so much.
She told Closer magazine: "I laugh at people who go to places just to be seen. At the start, I was told I should do that too but it`s fake and ridiculous to me, I don`t understand it."
