Paul Walker’s daughter, Meadow, shared the sweetest post in honor of what would have been her late dad’s 44th birthday on Tuesday, September 12.

“In honor of my dad’s birthday today, we’re challenging you to DO GOOD!” the 18-year-old captioned a photo of herself as a little girl dancing with her dad. “Share a video or photo of your random act of kindness and nominate 4 people to join the challenge! Be sure to tag the foundation as well as hashtag #PWFdogoodchallenge, so we can check out all of your posts! I nominate @marisamiller @vindiesel@meghanrochey & @lilchaseyk.”

Meadow (whose mom is Walker’s ex Rebecca Soteros) was only 15 at the time of her father’s death. The teen has taken on a passion for Paul’s philanthropic efforts. 

In 2015, she announced the official launch of the Paul Walker Foundation, which provides grants and scholarships to students and researchers pursuing marine science educations or working in the field.
