CNN -- Kim Kardashian and Kanye West are expanding their family again.

A source close to the couple told CNN Wednesday that they are expecting their fourth child via surrogate this year.

The couple welcomed their daughter Chicago West via surrogate last January. The couple also have daughter North, 5, and 3-year-old son Saint. Us Magazine was the first to report the news.
