Baby No. 2 on the way for Jack Osbourne!

Wow, that was quick! Jack Osbourne, 27, and his wife, raddestmom.com blogger Lisa Osborne, 26, are expecting another baby!

“I knew I was pregnant when all I could think about was Taco Bell and donuts right after I’d already eaten dinner,” Lisa tells People. She also shares that she's in her second trimester and "trying not to eat everything in sight."

This will be the second child for Jack and Lisa, who got married last October in Hawaii — the second grandchild for Sharon and Ozzy. They also have a 15-month-old daughter, Pearl Clementine.

"It's crazy to think we'll be a family of four," Lisa says.

Jack was in the news recently after being diagnosed with Multiple Sclerosis. Last summer, he went on his mom's talk show, The Talk, and said being a dad helped him cope with his diagnosis.

"When you get news like MS, it's a bit of a buzzkill," he said. "But having a baby is forcing me to focus on just that and my work, so it takes the sting away a little bit."
