Miami Heat

LeBron James was greeted by a massive swarm of fans trying to take his picture at an event in Shanghai, China on Wednesday.

Miami Heat star Chris Bosh adamantly denies sabotaging his baby mama's career on "Basketball Wives," TMZ has learned -- months after she accused him of turning the show's producers against her.

As we previously reported, Bosh's ex Allison Mathis claims she had brokered a $250,000 deal with "BW" producers to appear on the show -- but Bosh threatened to sue if that happened, so the producers caved ... and axed Allison after she had already taped two episodes.

But Bosh claims it's all BS -- firing back with his own legal docs in Orange County, Florida ... insisting it's not his fault producers decided to cut Allison from the show.

According to Bosh, whatever he may or may not have said to producers ... his intention was never to ruin Allison's career -- he was merely "acting to protect his own economic or financial interests."

As a result, Bosh insists he shouldn't have to pay Allison squat for the entire ordeal -- and wants a judge to trash her lawsuit.

It's all over a lawsuit the basketball star's ex-wife Siohvaughn Wade (right) filed a few months ago -- claiming her and Dwyane's kids were left scarred when Gabrielle and the Miami Heat guard engaged in "sexual foreplay" in front of them.

Both Dwyane and Gabrielle denied the allegations -- calling them "erroneous claims" -- and last week, a judge in Illinois officially dismissed Siohvaughn's lawsuit, citing improper jurisdiction.

Obviously, Cuban is referring to the fact that James decided to amp up the drama ... and screw with practically everyone's emotions ... before announcing on live TV last night that he was ditching the city that loved him to try and win a quick championship with a "super team" in Miami.
