Another West baby is reportedly on the way. 

According to a report from People magazine, Kim Kardashian and Kanye West are expecting their fourth child. The baby will be carried by a surrogate, and join 5-year-old North, 3-year-old Saint, and 11-month-old Chicago. TMZ reports the baby will be a boy, and is expected to be born in May. 

Chicago, who was also born via a surrogate, is less than a year old, but according to one "insider" the couple was quickly preparing for baby No. 4. “Kim and Kanye were already talking about baby No. 4 when Chicago was just a couple of days old," they said. "And they absolutely would use the surrogate again. They love her.”

Kim also revealed back in October that Kanye has been pressuring her to have seven kids. “Kanye wants to have more, though. He’s been harassing me,” Kardashian told her friend Larsa Pippen on Keeping Up with the Kardashians. “He wants like seven. He’s like stuck on seven.” 

At the time, the beauty mogul expressed how nervous she is to have more kids, especially in light of the increased number of school shootings. “That’s crazy. I could never, especially in like the world we live in,” she said. “I’ve been kind of hesitant about having more kids just because it literally keeps me up at night, thinking about how my kids will survive in a crazy world like this.”

If the couple is expecting their fourth, this might be their last, as Kim previously told Elle four is her limit. "My time is spread really thin," she said in March. "And I think it's important that in all couples, the mom give the husband as much attentions as the kids."
