Phoebe, 19, also had sweet words for her mother.

"Happy birthday to the most incredible woman. To know you is to love you," the Stanford University student captioned a pair of throwback images.

In addition to enjoying each other's company, Phoebe hasn't been shy about sharing how much her mom's work inspires her.

In a July essay for Vogue following the Supreme Court decision to overturn Roe v. Wade, Phoebe wrote that "when I started college last year, I wanted to become an advocate, like my mom."

"When you're Melinda's daughter, it's easy to be passionate about reproductive health. My mom is my hero," she wrote. "She's a brilliant reformer who travels around the world advocating for gender equality."

Phoebe went on to share that while she may be young, she's sure that "wherever" she ends up in life, she'll remain committed to the fight for women's rights.

"That, I hope, is the final legacy of Friday's decision: that it created a whole generation of pissed-off young people who will devote our lives to winning back a woman's right to choose," she wrote.
