Wilson announced the pregnancy Wednesday on her Bitch Sesh podcast, telling fellow comedienne Danielle Schneider, "Some big news on my end, which is that I am pregnant again."
The Happy Endings star shared that she is in her second trimester and is "so excited" to welcome her second child.
"I was feeling so for about a month but now I'm…not feeling great," she said.
Wilson and Caspe wed in May 2014 after dating for two years and are also parents to almost 2-year-old son Max Red.
Congratulations to the growing family!
