Seattle teacher Dan Jewett acknowledged his marriage to Scott this weekend on the couple's webpage for the Giving Pledge, a philanthropic organization which encourages the world's richest people to dedicate a majority of their wealth to charitable causes.

"I am married to one of the most generous and kind people I know — and joining her in a commitment to pass on an enormous financial wealth to serve others," Jewett wrote. "I look forward to the growth and learning I have ahead as a part of this undertaking with MacKenzie."

The Wall Street Journal first reported the marriage Sunday. Her Amazon biography also notes that Scott "lives in Seattle with her four children and her husband, Dan."

The marriage comes after Scott and Bezos divorced after a 25-year-long marriage. The divorce settlement made her among the richest people on Earth, currently holding a $53 billion fortune — according to Forbes — after receiving a quarter of Bezos' Amazon (AMZN) shares.

Scott has given away billions of dollars as part of a plan to donate a majority of her fortune. In December, for instance, she donated $4.2 billion to 384 organizations.

In a statement on the Giving Pledge's website, Scott said her philanthropic plans have not changed.

"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," she said.

Jewett indicated he plans to follow her lead. He said he intends to give away the majority of his wealth.

"I have been a teacher for the majority of my life, as well as a grateful student of the generosity of those around me," he said in the Giving Pledge post.

"This has meant doing my best to follow their example by passing on resources of all kinds—from time, to energy, to material possessions—when I have had them to give."
