Jack Osbourne's wife suffers "late term miscarriage"

Jack Osbourne's wife, Lisa Stelly, has suffered a miscarriage.

She revealed the news early Friday morning on her blog, Raddest Mom, in a post titled "Unfortunate Announcement": "I have been dreading this announcement. I needed some time before being able to say it. Jack and I lost our baby boy last week. Having a late term miscarriage is by far the hardest thing either of us have ever had to go through. We appreciate all of your prayers and ask for privacy and respect during this time. It's important to stay hopeful and optimistic through life's toughest moments. We never know why things like this happen. All we can do is trust in God and know he has a plan for our lives."

She later tweeted:

Osbourne, 27, married Stelly, 26, last October in Hawaii. They are parents to 16-month-old daughter, Pearl Clementine. In August, the couple announced they were expecting their second child.

Osbourne will compete in the upcoming season of "Dancing with the Stars," which kicks off Sept. 16.
