Last week, Kanye accepted the 2015 Shoe of the Year award for his adidas Yeezy Boost 350 at the Footwear News 29th Annual Achievement Awards.
“I’m waiting on my son to arrive any day now,” he told the crowd on Wednesday night in New York.
Baby Yeezus is the newest addition to the West family, which already includes two-year-old daughter North, who is ready to become a big sister.
“We read books with her about getting a baby brother and a new sibling all the time!” said Kim. “We always say goodnight to baby brother.”
Congrats to the couple!
