Lisa Stelly, the wife of 'Adrenaline Junkie' star Jack Osbourne, has announced that she is pregnant with their second child.

She made the exciting revelation earlier this evening (August 6) by posting a little message on her personal blog, which read:

"Jack and I are super excited to share with you all that we are expecting our second baby! I am in my second trimester, feeling great & trying not to eat everything in sight."

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

The pair welcomed their first baby, a daughter named Pearl (pictured below), back in April last year.
