Kim Kardashian vehemently denies booing Tristan Thompson at basketball game

ABC/Nicole Wilder(LOS ANGELES) -- Kim Kardashian came out swinging against rumors that she booed sister Khloe Kardashian's ex Tristan Thompson at a recent Lakers vs Cavaliers game.

Thompson plays for the latter.

Rumors sparked that Kim displayed unsportsmanlike conduct on Tuesday when video footage reportedly showed her heckling Thompson as he was shooting a basket.

"I was there to support him!," the shapewear mogul angrily tweeted on Tuesday in response to a Harper's Bazaar headline. "And was cheering screaming LETS GO TRISTAN!!!!!"

Kardashian, who was also attended the game with husband Kanye West, continued, "I would never go boo anyone. I don’t go to hate, only to cheer!"

Other photos taken at the event show Kardashian cheering and pumping a fist throughout the game.  The Cavaliers inevitably lost to the Lakers, 128 to 99.

Despite publicly announcing her support of the basketball star, the 39-year-old socialite has been critical of Thompson's relationship with her sister -- especially after his public falling out with the Kardashian-Jenner clan after he was caught cheating on Khloe. 

The ex-couple share a daughter, one-year-old True.
