The married stars will launch a brand new kid's clothing collection on Friday, Kardashian announced on Twitter.
"For the past few years Kanye and I have made almost all of our kids clothes and we have collaborated on a new kids line," she wrote Thursday.
"TheKidsSupply has been what we've been working on for a long time," she added. "I'm so excited about this!"
Kardashian and West, who have a 4-year-old daughter named North and a 1-year-old son named Saint, are no strangers to the fashion industry.
West, 39, already has an clothing line through Adidas, which includes his wildly popular Yeezy Boost 350 shoes that regularly sell out within minutes.
A price range for their kids clothing line has not been announced.
