She's 'A Mess!' Inside Kelly Osbourne's Secret Struggle With Ozzy & Sharon's Split — Why 'Everyone's Worried'

Despite reports that Sharon and Ozzy Osbourne's split could potentially be a cleverly orchestrated publicity stunt, sources claim daughter Kelly is "struggling" with her parents' cheating scandal.  

As Star readers know, reports claim Sharon kicked her philandering hubby of 34 years out of the house, after allegedly discovering his affair with hairstylist Michelle Pugh.  

"Kelly's a mess right now, and trying to deal with everything," insiders revealed to Now. "Kelly's really close to her dad and is struggling to believe he'd cheat."  

"She's trying to act as mediator, along with her brother Jack and sitter Aimee," the source further stated, adding that the Osbourne siblings are "desperately trying to salvage their parent's marriage and get to the bottom of what's happened."  

Now people close to Kelly — who struggled with drug and alcohol addiction in the past — are "worried" about the reality TV star not being able "to cope" with her parents split.  

"Kelly has been through hell and back over the years, and many of her issues stem from witnessing her parents' turbulent relationship," the source explained. "Kelly's far more vulnerable than people think and she's admitted that, when drama happens between her parents , she finds it difficult. It's worrying."
