Unbothered Tristan Thompson plays around with his teammates at his first game following accusations he cheated on pregnant Khloe Kardashian (Photos)

Khloe Kardashian's babydaddy Tristan Thompson made his first appearance since claims emerged he cheated on his pregnant girlfriend with three women.

On Wednesday night, the Cleveland Cavaliers NBA star played for his team against the New York Knicks at the Quickens Loans Area, and looked unbothered as he was pictured happily joking around with teammates despite his current cheating scandal.

But it was reported that Thompson, 27, who replaced LeBron James at the end of the first quarter during a timeout, was booed by some Kardashian fans as he was taken off the bench for the game.

Some also took to Twitter to troll Thompson as they watched him play last night.

'If I was at the Cavs game tonight I would buy so much food just to throw it at Tristan Thompson,' one woman wrote.

'The Cavs need to be giving solely Tristan Thompson updates. No one’s here for the score of the game,' another added. 

'I gotta say, Tristan Thompson looks unphased by this fiasco (sic). He still can't score and stinks overall at basketball,' a fan joked.

'Hard to play well when you’re thinking about the cheating you’ve been doing lmaoo #TristanThompson,' another added. 

'Instead of being called double T he should be double L cuz he lost his woman and can’t play basketball to save his life,' one Twitter user quipped. 

'Tristan Thompson is getting paid 16 million dollars a year to average 5.7 points and 6.6 rebounds a game this season...He played Khloe and the Cavs,' another added.

The New York Knicks defeated Tristan's club the Cleveland Cavaliers  110-98 in the basketball clash.
