The family of actor Paul Walker have shared some bittersweet messages today in honour of his 41st birthday.

The Fast and the Furious actor was killed last November when the car in which he was travelling as a passenger crashed into a tree and burst into flames.

Paul's brother Cody shared an old picture of the pair on Facebook today with a heartbreaking note.

"This day is a bittersweet one. Today I'm reminded how much I miss you," he wrote. "But at the same time, this day is also a reminder of how many years of memories, adventures, lessons and love I was lucky enough to share with you. Today is a celebration of all of those years."

"I always knew you were a pretty awesome brother, but these last months have shown me how awesome of an example you were for the entire world," he continued. "Thank you for always and for continuing to be the best role model a brother could ask for." 

Meadow Walker, Paul's 15-year-old daughter also shared a tribute on social media, posting a photo of her father holding her as a toddler with the message, "Happy Birthday, I love you."

Meadow lived in Hawaii with her mother until she was 13 before moving to California to be with her father.

Just weeks before his death, Paul spoke about the growing bond between himself and his daughter. "I'm glad I had her at 25, because at 40 and 15, we're matching up sweet," he told Us Weekly. "It's just working… It's perfect."
