Television personality Christopher Boykin, better known as “Big Black,” died Thursday at the age of 45, his representatives confirmed to numerous publications.

Big Black, who had previously served in the U.S. Navy, hit the limelight with his role as the bodyguard to professional skateboarder and TV host Rob Dyrdek. Both of them appeared on MTV’s popular series “Rob & Big,” which ran for three seasons from 2006 to 2008.

According to Celebrity Net Worth, Boykin had an estimated net worth of $3 million, most of which he amassed from his stint as the bodyguard on the TV show. The show was conceptualized after Boykin was hired as part of a sketch Dyrdek filmed for DC Shoes. Both of them reportedly got along very well and Dyrdek hired Boykin as his full time bodyguard.

“Rob & Big” ran for three seasons, but Boykin reportedly left after the birth of his daughter Isis Rae Boykin. In an interview with Graham Bensinger during an episode of his talk show, “In Depth with Graham Bensinger” last year, Dyrdek talked about the split, explaining why the duo put an end to the popular show.

"It was a strange period... I had been a pro skateboarder for years, so transitioning into mainstream fame was relatively smooth where for him it was the idea that he was working security two years earlier and now he’s on television," Dyrdek said. "It was a much different dynamic, but I think we both struggled with… I didn’t want to be known as Rob from ‘Rob & Big ,’ and I think he didn’t want to be known as the sidekick. So that created a lot of that tension between me and him."

The duo, however, made up recently.

Boykin launched his own clothing line in 2007. It was called Do Work. Starting with hats and t-shirts with the “BB” logo, Boykin’s merchandise launched an offshoot into plus sized men’s apparel, especially as Boykin himself was 6-feet-6 and weighed 375 pounds. The sizes available went from extra-large to 6X. Starting with men, the TV personality’s line also added t-shirts for women and children.

His death was mourned by a large number of fans and co-stars across social media.

His former partner Dyrdek wrote a number of heartfelt posts on Twitter, recalling the good times both of them shared together. In one tweet, he wrote, “We truly were brothers that lived an unexpected unforgettable adventure. I just can't fathom that it would end so suddenly.”

“You will forever be in my heart,” he wrote in another post.

Rapper Chanel West Coast, one of the hosts on Dyrdek's new MTV show, “Ridiculousness,” also took to social media to express her grief.

“RIP @bigblack1972. My heart is crushed hearing this news. I'll never forget all the times you made me laugh. So many epic memories with you. You put smiles on a lot of people's faces and you will be missed dearly by SO many. My prayers go out to your family and loved ones. Keep them laughing up in heaven,” she wrote.
