"Jack and I are super excited to share with you all that we are expecting our second baby!" Lisa Osbourne wrote.
"I am in my second trimester, feeling great & trying not to eat everything in sight. We feel so blessed that our family is growing & Pearl will have a little brother or sister to play with. It's crazy to think that we will soon be a family of four!"
Pearl was born in April 2012, and her parents married the following October.
