The Bezos divorce now is officially final.

Three months after Amazon founder Jeff Bezos and author MacKenzie Bezos announced reaching a divorce settlement, it was finalized by a Seattle-area judge Friday, Bloomberg reported.

The settlement leaves MacKenzie Bezos with a 4% stake in the online shopping giant worth more than $38 billion, according to Bloomberg, making her the third richest woman.

MacKenzie Bezos said in a tweet in April about the divorce that the Amazon CEO will retain 75% of the couple’s Amazon stock, along with voting control of his ex-wife’s shares “to support his continued contributions with the teams of these incredible companies,’’ she said.

Jeff Bezos, the founder of Amazon and owner of The Washington Post, remains the richest man in the world.

In late May, MacKenzie Bezos signed the Giving Pledge to donate at least half her wealth to charity. She is one of more than 200 philanthropists who have signed on to the initiative to encourage the world's billionaires to give away their wealth toward charitable causes.

In a letter posted to the website for the Giving Pledge, MacKenzie Bezos said she has a "disproportionate amount of money to share."

"My approach to philanthropy will continue to be thoughtful," wrote MacKenzieBezos. "It will take time and effort and care. But I won’t wait. And I will keep at it until the safe is empty."

According to Bloomberg, the court papers formalizing the divorce revealed little else about the terms of the separation. The couple filed a parenting plan for their children earlier this week.
