Bill and Melinda Gates announced this week that they will be getting a divorce after 27 years of marriage. 

According to recent reports, their split isn’t amicable and has even affected their three adult children, Jennifer, 25, Rory, 21, and Phoebe, 18.

Sources reportedly told TMZ on Thursday that “virtually everyone in the family took Melinda’s side.”

“First, we’re told this was not a friendly split,” the outlet reported. “We’re told Melinda and most of the family were furious at Bill for various things they claim he had done. Second … it’s clear this divorce has been a long time in the making.”

The Gates’ eldest daughter Jennifer also spoke publicly about the divorce, calling it a “challenging stretch of time for our whole family” in her Instagram Story after her parents’ announcement.

Here’s what else you need to know about the members of the Gates family

Bill co-founded Microsoft in 1975 with his friend Paul Allen, after dropping out of Harvard. The company launched its first IPO in 1986, which made Bill — who was 31 at the time — a millionaire almost overnight. 

He served as the CEO until 2000 but remained on the board until 2020 when he announced he would be stepping down so he could focus on the Bill and Melinda Gates Foundation.

Bill is also one of the wealthiest people in the world. Forbes estimates he is worth $129.1 billion. It is unclear at this point how the couple will settle their estate and how that will affect Bill’s net worth.

Melinda was working as a product manager at Microsoft when she met Bill in 1987, Fox News previously reported.

She worked her way up in the company, moving to marketing and then becoming the General Manager of Information Products in the early 1990s.

She married Bill in 1994, two years before Melinda left Microsoft so she and Bill could start a family. They went on to have three children.

In 2000, Melinda co-founded the Bill and Melinda Gates Foundation, which has since become the largest private charity in the world, according to Forbes.

When they announced their divorce on Monday, the couple said they planned to continue to work together on the foundation.

The Gates’ eldest daughter, Jennifer, is a competitive equestrian. She graduated from Stanford University in 2018 and started medical school soon after.

Last January, she announced her engagement to Nayel Nassar, 28, a native of Chicago who competes in equestrian events for Egypt, the homeland of his parents.

Jennifer has commented on what it was like growing up as the child of a billionaire.

“I was born into a huge situation of privilege,” Jennifer told Sidelines Magazine last summer.

“And I think it’s about using those opportunities and learning from them to find things that I’m passionate about and hopefully make the world a little bit of a better place,” she added.
