Looks like the 26-year-old has gotten fatherhood down pat.
Earlier this month Jack announced he had been diagnosed with multiple sclerosis.
A source told US Weekly, “He knew something was wrong for a while. Everyone is sad, but he is being strong about it.”
Jack also recently Tweeted a thank you to Montel Williams – who also has MS.
“Just wanted to say thank you to @Montel_Williams for the support. Means a lot.”
On an up note mom Sharon Osbourne told US she thinks Jack will excel in parenting.
“He’s very nervous — but nervous-excited,” she said. “He’ll be a very good dad. I think he’ll be very strict, but he’ll be a very good dad!”
