MacKenzie Bezos revealed Tuesday that she plans to give away at least half her massive fortune.

Bezos, the soon-to-be ex-wife of Amazon CEO and founder Jeff Bezos, joined the Giving Pledge, an agreement among some of the world's wealthiest people to donate at least half their money to charity in their lifetimes or in their wills. She is set to become one of the world's richest people, worth about $37 billion, once her divorce becomes final in about a month.

"In addition to whatever assets life has nurtured in me, I have a disproportionate amount of money to share," MacKenzie Bezos wrote in her Giving Pledge letter. "My approach to philanthropy will continue to be thoughtful. It will take time and effort and care. But I won't wait. And I will keep at it until the safe is empty."

The Giving Pledge mentioned her work along with Jeff Bezos in donating to marriage equality, cancer research, housing for the homeless and college scholarships for undocumented immigrants.

Jeff Bezos, who is the world's richest person, hasn't joined the pledge. He will be worth $114 billion after the divorce is final and will remain in the top slot.

"MacKenzie is going to be amazing and thoughtful and effective at philanthropy, and I'm proud of her. Her letter is so beautiful. Go get 'em MacKenzie," he tweeted Tuesday.

Her decision to join the pledge offers some clues about what she plans to do with her fortune when her divorce is final. She will receive 25% of Jeff Bezos' Amazon shares.

After being a minor player in the charity world for most of his career, Jeff Bezos in September unveiled the Day One charitable fund, with an initial investment of $2 billion to aid nonprofits focused on homelessness and to create a new network of preschools in low-income communities.

MacKenzie Bezos joined more than 200 other individuals and couples who are taking part in the Giving Pledge, which was started in 2010 by Bill and Melinda Gates and investor Warren Buffett. Bill Gates, who co-founded Microsoft, is listed as the second richest person in the world and Buffett is the fourth, according to the Bloomberg Billionaires Index
