Jack Osbourne's wife is paying tribute to her late father-in-law. Nearly two weeks after Ozzy Osbourne sadly passed away, his daughter-in-law Aree Gearhart took to Instagram to share some kind words and photos of beautiful moments with the rock legend. On Sunday, she wrote: "I'm pretty sure I have the coolest father in law around, and the best papa to my kids. The world got a rockstar but we got an ice lolly loving, goofy, big hearted guy who made us laugh like no other. He was always in my corner and I forever am thankful to him for raising my husband and blessing me w my family.
