Meadow Walker took time on Tuesday to pay tribute to her father, the late Paul Walker, on what would have been his 44th birthday.
The 18-year-old model shared an adorable throwback on Instagram of the two dancing when she was just a toddler, and promoted the Paul Walker Foundation Do Good Challenge, encouraging her followers to do a random act of kindness and nominate others to do the same.
"In honor of my dad's birthday today, we're challenging you to DO GOOD!" Meadow wrote. "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!"
