The Celtics guard agreed to the richest deal in NBA history — a record 5-year, $304 million supermax extension with Boston — on Tuesday amid reports that he’s dating social media influencer, Bernice Burgos.

Brown, 26, and Burgos, who is believed to be 43 years old, were first linked in September 2022, when they were reportedly spotted dancing together in a New York City pub.

In February, the NBA star and model were allegedly seen getting cozy on the beach, according to photos that emerged on social media at the time.

That month, Burgos also reportedly teased a Valentine’s Day celebration with a mystery man.

Burgos also stirred buzz on social media in April, when she shared videos from her romantic birthday celebration at Rare Steakhouse at Encore Boston Harbor.

Burgos, a Bronx native, is a mother and a grandmother who’s been linked to a number of celebrities and athletes.

She has two daughters, Ashley Marie Burgos, 27, who she welcomed when she was 15, and Sarai Burgos, 16.

Burgos became a grandmother when Ashley welcomed a daughter named India Ava Aisha in February 2018.

In a 2019 interview, Burgos told Hollywood Unlocked that she was hurt when she first became a grandmother “because I knew [my daughter] wasn’t ready [to have a baby].”

While describing her relationship with her oldest daughter, Burgos said, “It’s hard because I’m young and she’s young and we’re like sisters.”

Burgos, who has 7.2 million follower on Instagram, is a Fashion Nova ambassador and often shares photos and videos endorsing the celeb-loved brand.

She is also the CEO of her self-designed fashion line, Bold and Beautiful.

The brunette beauty was previously featured in music videos with a number of rappers, including Drake, DJ Khaled, J. Cole, Rick Ross and more.

Burgos was linked to Drake in 2015 when the pair were spotted together in Australia.

In 2019, Burgos told Hollywood Unlocked that she will always be friends with the rapper, but won’t date him again.

The pair reunited last week when the rapper performed at the Barclays Center in Brooklyn on his “It’s All a Blur” tour on July 19.

Drake shared a photo with Burgos on his Instagram Story, and wrote: “A lifetime ago w/ @realberniceburgos.”

She previously said she was a bartender at the same club where Grammy-winning rapper, Cardi B was a stripper in the Bronx.

Brown and Burgos have yet to address the ongoing romance rumors.

Reps for Brown and Burgos did not immediately return The Post’s request for comment.
