Kanye West and Kim Kardashian are expecting a baby girl.

The reality TV star -- who is pregnant with the couple's first child and due to give birth in early July -- is said to be "over the moon" after doctors confirmed they are having a daughter at her latest ultrasound scan.

A source close to the 32-year-old beauty told USMagazine.com: "They're over the moon! Kanye always wanted a girl."

The couple, who began dating in April 2012, announced they were expecting their first child in December.

The 'Kourtney & Kim Take Miami' star previously refused to say whether she would prefer to have a boy or a girl, insisting she only wanted the baby to be "healthy."

But she recently revealed that being pregnant hasn't had too much affect on her busy schedule or her diet.

She said: "I used to always say I can't wait to get pregnant because I will just eat whatever I want, but it's completely different. I'm like, OK, I want to eat as healthy as possible."

She also admitted: "I sleep amazing, it's like the best sleep ever. I'm a really easy sleeper though, you can put me on the couch with all these people in the room and say, 'You've got 10 minutes,' and I'll take an eight-minute nap."

Kim and her 'Mercy' rapper beau, 35, have already confirmed they will not allow their baby to appear on TV and also turned down $3 million for the first picture of the tot from a magazine.
