Vin Diesel & Rock pen emotional notes on Paul Walker’s birthday

Marking Paul Walker's 46th birthday, his 'Fast & Furious' co-actors Dwayne "The Rock" Johnson and Vin Diesel paid homage sharing special messages to the late actor.

The Rock, who was pretty close to Walker, took to social media sharing his feelings alongside a photo of his friend.

"I never post about my friend. It's a personal thing, but I prefer to keep our memories and bond private and quiet. But something about today compelled me as a moving reminder of how fragile life is for all of us. It's Paul's birthday and rightfully so, his legacy celebrated around the world," Johnson wrote alongside a photo.

Diesel on the other hand, wrote his message on Instagram in the manner of a letter. He wrote, "I reflect on how lucky I am to call you my brother. The tears never go away, but they change... from that of mourning to that of grace."

In November 2013 Paul Walker died following a car accident in Santa Clarita, California, at the age of 40. The actor has a daughter, Meadow Walker, who is now 20-years-old.
