It went wild because Stormi LEGIT looks like him, and doesn't at all look like Travis.
We mean, just look at this post from @exposingfavcelebs.
Now, however, Tim has come out and denied the rumours on his Instagram story.
"I am a very private person and would normally never answer to gossip and stories that are so ridiculous that they are laughable. Out of deep respect for Kylie, Travis, their daughter together and their families, I would like to set the record straight and say that my interactions with Kylie and her family have been limited in strictly a professional capacity only.
"There is no story here and I ask that the media no longer include me in any narrative that is incredibly disrespectful to their family."
We guess that puts an end to that theory.
