Phoebe Gates Keeps Her Love Life Under Lock & Key - Here's What We Know

Phoebe Gates has one of the most recognizable last names as the daughter of Microsoft co-founder Bill Gates and philanthropist Melinda Gates, but when it comes to her love life, she keeps it under wraps. Like her sister Jennifer Gates, who lives a lavish life thanks to her dad, she's inched toward the spotlight. Still, as her presence in specific social circles grows, she stands firm on what she shares publicly and what remains personal.

In December 2025, Phoebe Gates hard-launched her relationship on Instagram –- so you know it's official. She posted a photo of her and her boyfriend dressed up and cozied up, captioning the pic with a mere red heart emoji, but the sentiment was clear.

Now, the man in question? Her high school sweetheart, Chaz Flynn. The two met when they were 15 years old in Seattle, Washington and dated during their teenage years. There is no public knowledge as to why they broke up or how they reconnected; however, in September 2025, Gates opened up about their relationship on "The Burnouts" podcast. She mentioned Flynn's complete lack of social media presence, calling it "the best thing ever." She added, "I'm dating a guy who literally doesn't have Instagram ... Like, he deletes it. And it's amazing ... this is completely new for me. I've never been with someone like this."

Prior to her relationship with Chaz Flynn, Phoebe Gates dated another man who was no stranger to Hollywood headlines. In 2023, the entrepreneur began dating Arthur Donald, the grandson of Sir Paul McCartney. The two were spotted in Paris together, and Donald made a subtle appearance in her vacation photo dump, teaching everyone the way to soft-launch their relationship on social media (via Distractify). Even then, as the two attended the premiere of "Feud: Capote vs. The Swans" together, Gates still had yet to explicitly confirm the relationship.

However, in 2024, she composed a photo diary from her Stanford graduation day for Nylon, which included a pic of Donald giving her a piggyback ride with the caption, "My boyfriend, Arthur, giving me a lift post-ceremony." Though that was the couple's official "hard launch," they continued to keep their relationship low-profile, despite the massive awareness around their families. The occasional photos or interviews about certain quirks would surface, but the general public still wouldn't be able to spin stories about the pair. Perhaps it could be because of Gates' parents' public split, which had mom Melinda French Gates' post-divorce transformation turning heads, or simply a reflection of the privacy she wants for herself. Ultimately, this relationship, much like her others, was defined less by public opinion and more by the careful, controlled glimpses Phoebe Gates chooses to share.
