The new mum's "hot bodyguard" was forced to release a statement after rumours swirled last week that he was the real father of 3-month-old Stormi when fans flooded social media with side-by-side photos of the two.
Over the weekend Chung took to Instagram to share a message with his 755 thousand followers.
"I am a very private person and would normally never answer to gossip and stories that are so ridiculous that they are laughable," he began.
"Out of deep respect for Kylie, Travis, their daughter together and their families, I would like to set the record straight that my interactions with Kylie and her family have been limited in strictly a professional capacity only."
The security guard, who is also a member of the police department, asked that he be excluded from the narrative that is "incredibly disrespectful" to Jenner, Scott and her family.
Jenner, 20, and her boyfriend, who made their red carpet debut last week at the Met Gala, welcomed Stormi on February 1 this year.
