Jack Osbourne's pregnant wife Lisa Stelly headed to a doctor's appointment in Beverly Hills yesterday with daughter Pearl, and even though news of her pregnancy broke just yesterday, she's already sporting a noticeable baby bump!

"Jack and I are super excited to share with you all that we are expecting our second baby!" she wrote on her blog Raddest Mom.

We bet Pearl is excited to have a sibling!
