JACK Osbourne has reportedly finalised his divorce from wife Lisa Stelly - seven months after the pair confirmed their split.

The son of Sharon and Ozzy and his estranged spouse have "filed the final paperwork of their divorce", according to The Blast.

It's claimed Jack will share joint custody of their three children; Pearl, six, Andy, three, and six-month-old Minnie.

The publication also alleged that the reality star will pay "a very large amount of child support".

Jack and Lisa announced they were ending their six-year marriage with a joint statement on social media in May.

They wrote: "So, first and foremost, we absolutely still love each other.

"Our family is the most important thing in our lives, and we tried everything we could for many years to make this work.

"What's best for our family right now is that we separate lovingly, and remain best friends who are committed to raising our children together."

Despite their amicable split, TMZ reported in August that police were called on Jack after he punched Lisa's new boyfriend.

The reality star, 32, was reportedly left furious when the new man showed up at the home he shared with his ex as he tried to work on rebuilding their relationship.

However it appears the pair have since worked out their differences with Lisa attending Jack's 33rd birthday celebrations with the rest of his family last month.

The former couple also spent Thanksgiving together, with Jack and Lisa both sharing snaps of the family around the table on Instagram.

Ozzy, Sharon and Kelly - as well as their three daughters - were also in the picture, which Lisa captioned: "Thankful for my family. Everyday. #theosbournes #familydinner #momofgirls."
