According to US Weekly, the couple is expecting a girl. "They're over the moon," a source close to the pair tells the magazine. "Kanye always wanted a girl."
In December, Kardashian, 32, and West, 35, announced they were expecting their first child together. The couple was first publicly linked last spring, though Kardashian is still legally married to NBA player Kris Humphries. She filed for divorce from him in late 2011, but Humphries is seeking an annulment. Their divorce trial is scheduled to begin in May.
The baby is due in July.
