Jack Osbourne and wife Lisa have lost their baby.

The blogger, 26, who was in her second trimester, shared the sad news early Friday morning.

“I have been dreading this announcement,” she writes on her blog, Raddest Mom. “I needed some time before being able to say it. Jack and I lost our baby boy last week.”

She continued, “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.”

Two hours after the announcement, Lisa Tweeted, “Cuddling my amazing, sweet hubby and shutting my eyes. Thank you all for the love and support. It means the world.”

The pair had been in the midst of much happy news as of late. “I am feeling great and trying not to eat everything in sight,” Lisa told PEOPLE last month.

Earlier this week, Jack, 27 — who was diagnosed with multiple sclerosis in 2012 — was named to the cast of Dancing with the Stars, beginning its season Sept. 16.

The couple were married in Hawaii last October and are parents to daughter Pearl Clementine, 16 months.
