The model announced the news in her typical fashion – via Twitter, of course.
“Somebody’s herrrrrre!” she penned, along with baby bottles and other themed emojis.
This is the second child for the couple, who welcomed their Instagram famous daughter Luna in 2016.
The star has been very open abut the ups and downs of pregnancy on her social media platforms; she tweeted earlier that month that she was already ready to be done with pregnancy. Really, who can blame her?
“happy pregnant Chrissy is gone. meet OVER IT Chrissy,” she wrote on her Twitter. “Wanna hold my boy let’s do thisssssss”
Her original due date was in June, so at least she got out a week or two early. For now, congratulations are in order!
