Boston, Massachusetts - Following NFL star Aaron Donald, Jaylen Brown of the Boston Celtics has become the first NBA player to sign with Donda Sports marketing agency, rapper Kanye West's newest business endeavor.

"A beautiful collaboration," as Jaylen Brown calls it.

The NBA All-Star revealed in an interview Wednesday during NBA Finals media day – just prior to his Game 1 against the Golden State Warriors on Thursday – that he has officially signed with Kanye West's marketing agency, Donda Sports.

"It was time," Brown said. "For me, like I said, anytime I make a life decision, I contemplate. I think about things deeply. And from what I want to do, the missions I want to get accomplished, it was the right decision."

Recently, Brown became a free agent for shoe deals after his long-term deal expired with Adidas, who signed him before his rookie season in 2016.

As an active advocate for social justice causes, the athlete said he prefers future endorsement deals to include investments in those areas.

"I'm looking for a shoe company that's progressive, cutting edge, that keeps an open mind, that's also leaning towards doing things in the community, as well environment friendly, sustainable, recyclable, biodegradable products," he said.

"I'm looking for the brand of the future, not the brand of the past."

Brown, who was seen posing for pictures with West courtside earlier this season, becomes the first NBA player to join the growing sports agency that is expected to handle all his marketing deals.
