The 25-year-old was touched by Simpson's words and says women in the music industry need to be supportive of one another.

She explains, "Recently, I was staying at a hotel when I got a letter from Jessica Simpson, who was in the penthouse across the hall. It was super complimentary.

"She said my voice and my artistry were pushing her. I was touched, because that's so rare in this business, which stirs competitive nature and cattiness in women.

"Hats off to Jessica -- that was a cool move. It's a beautiful quality to be a woman in support of other women. The world needs more of that."
