This post has been updated with new information.

Christopher "Big Black" Boykin passed away at age 45 on Tuesday, The Hollywood Reporter confirmed. While Christopher's cause of death has yet to be officially revealed, TMZ reported on Wednesday that the star of MTV's Rob & Big was dealing with heart issues prior to his death. According to Christopher's ex-wife, Shannon Turley, Christopher was hospitalized in Plano, TX, for several days while doctors monitored his heart and already had a defibrillator implanted in his chest. Doctors tried to resuscitate him for 30 minutes when his heart gave out on Tuesday, and he died at 4 p.m. Chris was not on the transplant list yet, but doctors said he was headed in that direction. Christopher is survived by his 9-year-old daughter Isis, who he shares with Shannon.

Big Black is best known for his role in the MTV series and as Rob Dyrdek's bodyguard and close friend. His former costar Chanel West Coast confirmed the news on Twitter moments after, writing, "RIP @BigBlack. My heart is crushed. I'll remember all the times you made me laugh and my prayers go out to your family." Rob also paid tribute to him in a beautiful way on social media shortly after, posting a series of photos of the pair along with a touching note. Our thoughts are with Christopher and his family.
