Celebrations for the nuptials of the medical student and the Egyptian show jumper appear to be ramping up, with Jennifer this week marking her bridal shower.
The eldest daughter of Microsoft founder Bill Gates and his former wife Melinda shared snapshots from the occasion on social media on Tuesday, thanking her mother for organising the event.
"Thank you for this incredibly special celebration, Melinda French Gates," wrote Jennifer, 25.
"So deeply grateful for all the amazing women in my life who advise, support and uplift me. Cheers to this new chapter!"
In the accompanying images, Jennifer and Melinda are seen mingling with guests on a lawn, as well as sitting down to eat at a long outdoor dinner table. The colour scheme for the shower revolved around a dusky pink, with pink velvet chairs used for dinner and floral arrangements featuring roses and pastel pampas grass.
The bride-to-be also wore a rose-coloured pashmina over her white dress with cut-out detailing.
The event is believed to have taken place at the Washington mansion Bill and Melinda shared before their separation. The couple announced they were set to divorce in May, after spending 27 years and welcoming three children together.
Jennifer and Nassar, 30, who represented Egypt at the Tokyo Olympic Games earlier this year, announced their engagement in January 2020. The couple have been together since 2018, and got engaged during a skiing holiday.
"Nayel Nassar, you are one of a kind. Absolutely swept me off my feet this past weekend, surprising me in the most meaningful location over one of our many shared passions," Jennifer wrote on Instagram at the time. "I can’t wait to spend the rest of our lives learning, growing, laughing and loving together. Yes a million times over."
The couple have not confirmed a date or a location for their wedding.
