Rose is currently expecting her first child with fiancé Wiz Khalifa and joked in an interview with XXL that she wants to be able to use her labour to her advantage.
"I'm so ready," People quotes her as saying. "I've decided that I'm going to have an all-natural water birth. No medicine."
Rose added: "I want those bragging rights! The next time Wiz has a stomach ache or anything, I'll say, 'I popped out a baby all-natural'."
However, Rose admitted that she has not had an easy pregnancy, saying: "My first trimester was really hard, like most women. I threw up a lot. I was very, very, very sick. I'm still sick now in my second trimester.
"I just feel like I learned a lot just being pregnant this time. For my next baby, I'll know what not to eat and things to stay away from. Definitely the smell sensitivity is still very strong. Certain things, as soon as I smell them, I throw up immediately."
Rose previously revealed that she fell in love with Khalifa thanks to Twitter.
