According to a close source
"Amber and Wiz Khalifa unexpectedly got pregnant, but they're really happy to be starting a family together. Amber's already had to make some big lifestyle changes, like not smoking cigarettes anymore. As a model she's used to having a thin waist, so this is going to be an adjustment for her."
Amber wants to move up their wedding date to October to avoid getting married when she is heavily pregnant.
Rapper Wiz proposed to Kanye West’s former girlfriend earlier this year and although the pregnancy was a surprise, the pair are said to be thrilled about the baby.
