Ludacris appeared in "2 Fast 2 Furious" and "Fast & Furious 6" with Walker and attended the actor's private funeral Saturday at Forest Lawn Memorial Park in the Hollywood Hills.
Following the ceremony, the rapper posted on Instagram the service's program, which featured a black-and-white image of Walker with the words "Always in our hearts …" and the dates of his birth and death.
Walker died Nov. 30 after the Porshe he was riding in crashed into a tree and burst into flames.
Fellow actor Tyrese Gibson -- who was also in the second and sixth installments of the film franchise, and was currently filming "Fast & Furious 7" with Walker -- was also at the funeral.
He too posted a black-and-white photo of Walker on his Instagram account with a lengthy caption.
"Today In a room full of your loved ones I wish today was your wedding instead.... God has a better plan even beyond ALL of our own understandings...... For selfish reasons we all wanted you to stay, another laugh, another take, another talk, another moment..... I guess you can't get all you ask for in life.... But our hearts are FULL from all the moments we DID have, 13 years of laughter and grace, humility and love..... Never did I take my access for granted.... Continue praying for his #Family, his daughter #Meadow, you are the WORLDS best friend that's why we're all feeling it...#RIHAW •Rest In Heaven Angel Walker•," Gibson wrote.
