Bill and Melinda Gates said Monday that they are divorcing but would keep working together at the Bill and Melinda Gates Foundation, one of the largest charitable foundations in the world.

Axar.az reports in identical tweets, the Microsoft co-founder and his wife said they had made the decision to end their marriage of 27 years.

"We have raised three incredible children and built a foundation that works all over the world to enable all people to lead healthy, productive lives," they said in a statement. "We ask for space and privacy for our family as we begin to navigate this new life."

Bill Gates was formerly the world's richest person and his fortune is estimated at well over $100 billion. How the couple end up settling their estate and any impact on the foundation will be closely watched, especially after another high-profile Seattle-area billionaire couple recently ended their marriage.
