The 32-year-old reality star has daughters Pearl, six, Andy, two, and Minnie, three months, with Lisa Stelly, but on Friday (18.05.18), she allegedly filed papers to terminate their six-year marriage, according to The Blast.

Lisa, also 32, and Jack married in 2012 in a small ceremony in front of less than 50 guests, including Jack's famous family - sister Kelly, and parents Sharon and Ozzy.

The reported split comes just three months after the couple welcomed their third daughter Minnie into the world, and announced the news on social media.

Jack shared a photo of their new arrival next to a board which listed her full name as Minnie Theodora Osbourne, as well as other information such as her time of birth, which was 5:57 AM.

He captioned the sweet snap: "Hey everyone meet Minnie! She's the newest member of my girls only squad. (andy stole the "i" from inch) #girlsrule #playerscurse #happydaddy#hatchling (sic)"

Lisa shared the same photo on her own Instagram account, and captioned it: "The final member of my little girl squad. Everyone, meet the angelic, miss Minnie (sic)"

Kelly Osbourne also shared the snap on her account, where she congratulated the pair on their new arrival.

She wrote: "Congratulations to my brother @jackosbourne & his beautiful wife @lisaosbourne on the birth of #MinnieOsbourne. She is perfect in every way. It was such a beautiful experience to witness the birth of this angel. I love you both so much. #ProudAuntie (sic)"

Previously, the couple announced they were expecting a third child when Lisa took to Instagram to share a photograph of her and Jack standing in front of the mirror with her blossoming baby bump clearly on display just before an apparent date night.

She teamed the sweet picture with the funny caption: "Literally ate the biggest burrito ever (sic)."
