Alaskan country singer Jewel has offered some advice for a fellow blonde – 28-year-old former reality TV star Jessica Simpson.

With 27 million albums under her belt, Jewel Kilcher says that Simpson’s debut into the world of country music should be interesting – as long as she remembers to “work hard and be authentic.”

Simpson’s as-yet-untitled Nashville LP is due out in early September.

“I really like Jessica. She’s always been such a sweet, sweet person,” says Jewel. “If I were going to give her any advice, I would say work hard and be authentic. Be true to who you are. The thing about country music is its fans have an excellent authenticity meter. They can spot bullshit a mile away. Anyone who comes to country music just to dabble in it, or who doesn’t know it or respect it as a genre and respect its history and tradition, is not going to make it.” According to Simpson, this isn’t a fad. “I’m planning on making country music for the rest of my life,” she’s claimed, “and I don’t want to go back to that other world.”
