Jack Osbourne spoke about his relationship with sister Aimee Osbourne before she made a rare public appearance at Ozzy Osbourne's funeral. "We're not close at all," Jack, 39, said during an appearance on the "Disrespectfully" podcast last month. "We don't have a great relationship. She'll be the first to tell you that. So, it's no secret." Aimee, 41, never appeared alongside her family on The Osbournes reality show. According to Jack, she wanted to be an "obscure mysterious moody" musician.
