Baby No. 2 is on the way for Jack and Lisa Osbourne – which means another grandchild for Ozzy and Sharon!

“Jack and I are super excited to share with you all that we are expecting our second baby!” Lisa posted on her blog, Raddest Mom, along with a family photo.  “I am in my second trimester, feeling great and trying not to eat everything in sight.”

The couple, who were married last October, are parents to daughter Pearl Clementine, 15 months.

“We feel so blessed that our family is growing & Pearl will have a little brother or sister to play with,” the expectant mom added. “It’s crazy to think that we will soon be a family of four!”

The happy news doesn’t exactly come as a huge surprise, as it’s no secret that the couple wanted more children.

In April, Sharon told PEOPLE that her 27-year-old son “wants about five kids and Lisa comes from a big family, too. They both want to have a whole brood.”

Looks like their wish is coming true!
