Vin Diesel and Meadow Walker took to Instagram on Tuesday (September 12th) to remember Paul Walker on what would have been his 50th birthday. The Varsity Blues actor died in a car crash at the age of 40 in 2013.

“Happy birthday to my guardian angel,” Meadow wrote, alongside an old picture of herself with her father. “You taught me at a young age to always treat everyone with respect, to do good and to take care of our planet. I love you and miss you every day.”

Paul’s Fast & Furious costar, Vin Diesel, also honored him on Instagram with a lengthy post. “A decade… ten long years… and yet it feels like yesterday when we were singing happy birthday to you for the big 40!” Diesel wrote alongside a throwback photo of the pair together. He added, “For me this picture represents the moment I knew we would be brothers for eternity.”
