Kemper and her husband Michael Koman welcomed their son on September 5. The actress shared she was pregnant back in May. She didn't announce in an adorable way, nor was she planning on sharing the news at the time that she did. She was on Jimmy Kimmel and he called her out for missing a party that he threw. He was wondering why she did not make it to his party. She shared that she didn't want to tell anybody but there is a reason that she missed his party. She said that she is so sorry for missing his party but she is pregnant. She said that she was extremely sick during his party and she didn't want to go to his party when she felt so terrible. She then went on to explain that she missed a lot of things due to her pregnancy.

The couple got married in 2012. They had their first child, James, in 2016. He is now three years old. Kemper announced the pregnancy of her first child when she was on The Tonight Show with Jimmy Fallon. She is always quick to gush and brag about her son James. She explains how her son is a genius. She said that her son has started to master a whole bunch of words and he has learned how to mimic and imitate words that she says. She said that he is so impressive. She shares that he is the smartest person on the plant.

We are so happy for you on the new baby! Congratulations on baby number two! We hope that everything is going well and that the little boy is perfect and healthy!
