Jessica Simpson drinks snake sperm to improve vocals, says it tastes like 'honey'

"Discovering this music is something I did on my own," Simpson recently told People magazine. "Thank God I had Nashville, it was just a way of me owning myself and declaring it."

Simpson described her first single, "Use My Heart Against Me," as "a sexy song to write."

"I woke up with that lyric in my head," she said. "It's kind of craving someone that you want again, and you don't care if your heart is used against you - if it's just for one night. Like, give it over, just for the experience again."

"I didn't necessarily want it at the beginning of writing this record. I was in a different place," she continued.

"I am a woman now, and I can do what I want and to have freedom in music - I think that's what you're going to feel in 'Nashville Canyon.'"

"I was never going to win because I had someone like Britney [Spears] and Christina [Aguilera] ahead of me, who were selling so many more records," Simpson said. "I didn't want to dance, I didn't want to wear a head mic. But I agreed to do it because I worked for Sony, and I didn't want to let them down, and I felt like I was constantly letting people down, even myself, probably because I wasn't singing words I wrote."

Following the advice of her then-manager, Simpson began writing her own songs and hit number one with her pop hit, "With You."

"When I've had success in my life is when I've just been honest and real," she told the outlet. "I've never gotten a chance to do that in music until now."
