Jessica Simpson, the American actress and singer, shared the secret to her fantastic vocals: cockroach sperm.

The artist posted a video on Instagram, where she showed that she drinks "snake sperm" on the recommendation of her vocal coach. 

The video showed Simpson drinking the Chinese herbal drink while explaining the purpose of her action to the bewildered group of assistants. 

When asked if the not-so-common drink was similar in taste to tea, she compared it more to honey. 

Ultimately, Simpson said the drink improved her singing voice. "If you want good vocals, you should drink snake sperm," she advised.

Last month, Simpson confessed for the first time in an interview that giving up alcohol forever changed her as a musical artist.

"The moment I started drinking heavily was when I started writing music in 2016 and I was ending up in situations where I started feeling sorry for myself," she said.

Jessica Simpson celebrated her seventh anniversary of quitting alcohol in November 2024. "I'm actually a lot calmer without alcohol and I actually have a lot more confidence in myself without it," she said.
