UNDATED (CNN) -- Reality TV star Kim Kardashian and her boyfriend, rapper Kanye West, are having a baby girl.
The baby's gender was revealed on the eighth-season premiere of "Keeping Up with the Kardashians," Sunday night. The episode shows the 32-year-old Kardashian at a doctor's appointment for her 19-week checkup.
When the doctor says he thinks it's a girl, Kardashian asks for a percentage to which the doctor says, "99-plus."
The baby is due next month. News of the gender went public the same day Kardashian had a baby shower in Beverly Hills.
