Jennifer Gates is PREGNANT! Bill Gates' daughter expecting first child with Nayel Nassar - Daily Mail

The 26-year old daughter of billionaire Bill Gates and his ex wife Melinda revealed the happy news on Thanksgiving as she debuted her bump while posing with fellow equestrian Nayel, 31.

Baby joy: Jennifer Gates is expecting her first child with husband Nayel Nassar.

Proud grandmother-to-be Melinda, 58, wrote: 'I couldn't be more excited to meet this little one and watch you two become parents.'.

Both Bill and Melinda were there to walk Jennifer down the aisle on her big day last fall, putting differences aside in the midst of their high-profile divorce.

Melinda shared one of the first photos shortly after the nuptials, showing the moment she and Nayel walked back up the aisle on October 16 2021, moments after being pronounced husband and wife.

The photo was taken after the couple's second set of vows, which followed a smaller religious Muslim ceremony in the garden of the family's 142-acre estate in North Salem, New York. .

Jennifer proudly posted the wedding photo on Instagram early Monday afternoon, adding the caption: 'My universe 10.16.21.'  .

First grandchild; Proud grandmother-to-be Melinda, 58, wrote: 'I couldn't be more excited to meet this little one and watch you two become parents'.

So happy: Melinda said she 'hadn't stopped smiling' since the pregnancy reveal.

So grateful we were able to find a way to safely gather for this special day,' she wrote, captioning a photo of Jennifer and Nayel posing together outdoors. .

The wedding weekend also involved a wind-down brunch, catering by renowned New York City restaurants, and performances by Coldplay.

The ceremony was performed by a longtime family friend, and the bride and groom wrote their own vows.

The extravagant two-day event, costing an estimated $2 million, was orchestrated by famed wedding planner Marcy Blum, whose elite client list includes Kevin Bacon, LeBron James, and Billy Joel. .

'Planning a wedding while I was in medical school rotations and Nayel was preparing for the Olympics was no small feat,' she said

Jennifer also told Vogue she required all 300 of their wedding guests to be vaccinated and take COVID tests, she said, in order to ensure everyone's safety

The Gates had a string of luxury mansions across the US - including Florida, California, and Wyoming - but their main family home was in Washington, near the Gates Foundation headquarters. 

They also founded the Bill & Melinda Gates Foundation together in 2000, and even after going their separate ways, the former couple continued to run the foundation together - which Melinda said helped her get through it
