Just two weeks after he and fiancée Lisa Stelly welcomed daughter Pearl Clementine, Osbourne, 26, was dealt the shocking news. In an exclusive, sit-down interview and photo shoot with PEOPLE magazine, Jack and his mother Sharon open up about their emotional ordeal.

“I was just angry and frustrated and kept thinking, ‘Why now?’ ” Jack tells PEOPLE.

As always, a few kind souls couldn’t resist kicking Jack while he’s down.

@MrJackO Do you think you might have done too many drugs when you were a toddler?
