The former couple share daughter Meilani Alexandra, 5, and son Grayson Valor, 3.
Details of their divorce, including custody and spousal support agreements, have yet to be revealed.
The MTV star admitted on a recent episode of Jersey Shore that she couldn't wait for their divorce to be final.
"The last thing I want is this divorce to drag out. Thankfully, we have the prenup, because this thing can’t end soon enough," she told costar Nicole "Snooki" Polizzi.
The mother-of-two hinted at her excitement over her divorce being finalized by posting a throwback photo of an elated Nicole Kidman to her Instagram account.
