The death of Paul Walker has caught everyone off guard and has deeply affected his closest friends and family. In fact, one of the most heavily shared links for the past couple of days have been pictures of a saddened Tyrese Gibson, paying his respects to Paul Walker at the site where a terrifying Porsche Carrera GT crash took his life.

Grief from the loss of a love one is extremely difficult to express. In a courageous attempt to celebrate Paul Walker's life, friends and costars Tyrese Gibson and Chris 'Ludacris' Bridges worked with hip hop group The Roots to release a new song called "My Best Friend." Tyrese and Paul Walker first worked together for "2 Fast 2 Furious" nearly 10 years ago. In fact, the two actors have been extremely close friends for 13 years.

"My heart is hurting so bad no one can make me believe this is real," Tyrese shared on Facebook with an accompanying photo. "Father God I pray that you send clarity over this cause I just don’t understand My heart hurts it’s broken no one can convince me that this is real…. Prayer warriors please pray real hard for his only child, his daughter and family…#HeartOfAnAngel13YrsFamilyForeverWeJustCelebreatedYour40thBirthday….. My God… My God… I can’t believe I’m writing this."

Beyond Paul Walker's Fast and Furious family, other famous friends of Paul Walker have used the medium of music to cope with the unexpected loss as well. Rapper RZA of the Wu-Tang Clan also shared a new song, "Destiny Bends," dedicated to Paul Walker.

"This song, entitled "Destiny Bends" was written last night after hearing the tragic news of the loss of a good man named Paul Walker. I met Paul on the set of the film Brick Mansion, where we talked, laughed, and exchanged ideas of life and fatherhood," said RZA. "I only knew him personally for less than a year, but we knew each other through our work and art. We saw in each other a kindred spirit of men coming from unlikely circumstances, and rising to be the light and beacon of our family and loved ones. Men who learned the joy and pains of love in life, and success, while coming to realize that nothing is more important than family, friendship, and the brotherhood of humanity. Millions of people get to know an artist or movie star through their work, but few are allowed to cross each others' paths and see through the veil of stardom and find the common denominator that we share. As all physical things will decay and wither away, film, art, and music remain longer than the vessel that delivered them. In this vein, the one thing we can't take away or give back is time. So, thus, time is the most precious gift. I dedicated my time to compose this song with my two sons and new friend Will Wells, who was kind enough to sing and perform it for me. We dedicate it to Paul Walker. A good man. We had plans to continue working with each other in the future. It seemed destined, but 'destiny bends.'"
