Kanye West is thrilled by all of the Kardashian/Jenner pregnancies.

The 40-year-old rapper and his wife Kim Kardashian West are expecting a third child via surrogate, while his sisters-in-law Khloe Kardashian and Kylie Jenner are also reportedly pregnant and Kanye, who is an only child, is over the moon.

A source told PEOPLE: ''I think Kanye is even more excited than Kim. He was an only child; he didn't have a bunch of kids around. He's been very honest about how lonely that could be for him.

''And now there will be three siblings, along with a huge extended family. This sounds like a dream come true for him.''

Kim recently confirmed that she and Kanye - who have daughter North, four and 21-month-old son Saint together - will welcome a new baby via surrogate.

And she is delighted that she and her sisters will be having children at the same time.

The source continued: ''There is no jealousy here. No one is worried about anyone stealing their thunder. It's not dramatic like that.

''Kim is really into the idea of a bunch of babies being born around the same time. She think they'll be more like sisters than cousins. Everyone in the family is just thrilled about the whole thing.''

However, the entire family were reportedly upset at first when Kylie, 20, got pregnant.

The insider said: ''No one was thrilled about Kylie because she's so young and naive, but everyone has come around and they are focusing on the baby.

''They truly believe that Kylie will rise to the occasion and be a good mom. And they'll be there to help!''
