Pregnant heiress Jennifer Gates proudly showed off her baby bump as she attended a wedding alongside her younger sister, Phoebe Gates, and her billionaire dad, Bill Gates.
The aspiring doctor, 28, announced that she was expecting her second child with her equestrian husband, Nayel Nassar, last month.
Now, she has showcased her growing stomach while celebrating the nuptials of some friends.
Taking to her Instagram Stories on Sunday, Jennifer shared some snaps from the wedding - and one showed her cradling her baby bump alongside her partner, 33.
Dressed in a light pink patterned maxi dress, Jennifer placed one hand on her belly and the other around Nayel as they smiled towards the camera.
Another featured her looking lovingly at the Olympic showjumper, who donned a gray suit.
A third image saw the expecting mother posing with her dad and younger sister.
68-year-old Microsoft founder Bill, whose net worth is estimated at $135 billion, opted for a navy suit while aspiring designer Phoebe, 21, donned a haltered pink mini gown.
Jennifer kept her long, red hair in loose waves while Phoebe chose to pull her dark brown locks into a slicked back ponytail.
Jennifer revealed that she was pregnant in late June - just 16 months after she and Nayel welcomed daughter Leila.
She shared the news via Instagram, posting a photo that showed her holding hands with the toddler and showcasing her baby bump in a blue ensemble.
'Leila, being promoted to big sister,' she wrote in the caption.
Jennifer's mom, Melinda Gates, was quick to show her support as she shared the post to her own Instagram alongside a caption that read: 'I am so excited for Jennifer, Nayel, and Leila.'
It's certainly been a busy 2024 for Jennifer already, as she graduated from medical school earlier this year - and the ceremony brought her estranged parents together for the first time in months.
'Dr. Gates, MD, MPH. Can't believe we've reached this moment, a little girl's childhood aspiration come true,' she wrote on Instagram in May alongside a snap of her in her cap and gown alongside her parents and husband.
'It's been a whirlwind of learning, exams, late nights, tears, discipline, and many moments of self-doubt, but the highs certainly outweighed the lows these past five years.
'I am deeply grateful for this experience and so indebted and thankful to my professors, mentors, friends, and family for their endless support along the way.'
Jennifer and her husband, Nayel, met while competing internationally on the equestrian horse circuit, and their friendship eventually evolved into romance.
The Egyptian-American equestrian was born in Chicago and raised in Kuwait. His millionaire parents, Fouad Nassar and Iman Harby, are the owners of the architectural firm Diwan Interiors International in Kuwait.
The couple, both Stanford graduates, officially started dating in January 2017, and they wed in October 2021 during a private religious Muslim ceremony at the family's 142-acre estate in Westchester County.
The next day, they threw a huge celebration at Jennifer's $15.8 million home in North Salem, New York - a 124-acre horse farm that was a college graduation gift from her billionaire parents.
Jennifer also owns a $51 million Manhattan penthouse, another present from her parents.
The 8,900-square-foot, three-level apartment was previously owned by Lewis Hamilton and is the largest in a starry luxury apartment building at 443 Greenwich Street.
It boasts six bedrooms, six baths, two powder rooms, 20-foot-high ceilings, multiple terraces resulting in 3,400-square-feet of outdoor space, and two parking spaces.
