Jewel – who has sold over 27 million albums worldwide – advised Simpson, 28, to “be true” to herself when her debut country record hits stores in September.

“I really like Jessica. She’s always been such a sweet, sweet person. 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 bulls**t 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.”
