The model was rumoured to be pregnant over the summer (12) and she officially revealed she was expecting her first child earlier this month (Sep12) by attending the MTV Video Music Awards in a figure-hugging lace dress.
Rose has now shown off her growing belly on the front of Xxl magazine, posing in a rolled-up vest top and knickers as she cuddles up to Khalifa.
She also reveals she is planning a water birth, as she wants an "all-natural" delivery for her first child.
Rose says, "I'm so ready. I'm going all-natural. I've decided that I'm going to have an all-natural water birth. No medicine.
"I want those bragging rights! The next time Wiz has a stomachache or anything, I'll say, 'I popped out a baby all-natural.'"
