Osbourne and Wilson have known each other for years—Slipknot toured with Ozzfest, the music festival founded by her parents, Ozzy and Sharon Osbourne.

Osbourne opened up last year about her struggle with sobriety and wanting children earlier in life. She says, "My brother has three daughters and I would have loved to have kids by now, but that wasn't what was in the cards for me yet."
