A true family celebration.
While stepping out for the festive evening, Melinda, 59, wore a casual dress while the Microsoft co-founder, 67, opted for a brown collared sweater and slacks. Phoebe, who has been seen wearing an array of glamorous outfits during New York Fashion Week, donned a pink mini dress with heels and wore her hair slicked back into a high ponytail.
The former spouses, who announced their separation in 2021 after 27 years of marriage, were previously seen together while attending daughter Jennifer’s graduation from Columbia University in May. At the time, Jennifer, who welcomed her first baby in April, shared a photo of herself on Instagram in her cap and gown smiling with her parents as well as husband Nayel Nassar.
Earlier in the day, the proud parents also shared tributes in honor of their youngest’s big day.
“Happy birthday, @phoebegates! You’ll always be my little girl, but watching you do big things has never surprised me,” Bill wrote on Instagram alongside a series of throwback father-daughter shots.
Meanwhile, in a FaceTime call shared on Instagram, Melinda gave her daughter advice for her 21st year. She told Phoebe to remember that she knows herself "a lot" and to not "ever forget who you are."
“I love you so so much,” the philanthropist and global advocate added.
Phoebe’s milestone birthday capped a seemingly fun week for the mother and daughter.
In a "fashion week wrap up" Instagram post shared on Wednesday, Phoebe highlighted some behind-the-scenes moments from her chic week — including a shot of her and her mom.
