Lisa Osbourne went on her blog, Raddest Mom, to elaborate.

"I'm pregnant! Pearl is very happy to become a big sister," she wrote. "She diligently reads her 'I’m a big sister' books every night and recites to me her plans of bathing, feeding, singing to, and holding the baby. We are more than halfway through this thing and are very excited to be parents again!"

Jack's sister Kelly Osbourne also shared her excitement on Twitter:

Congratulations to the family!
