According to Daily Mail, Rojean has flaunted her connections with Travis on social media, even goading Kylie with photos of herself in the same location as him.
And Kylie has clearly been riled.
Back in March, Rojean tagged Kylie in a post to reveal the Keeping Up With The Kardashians star had blocked her.
She wrote: "How many times a day do you block & unblock me girl," following it up with laughter emojis.
She also one posted a sexy snap of herself in bed, and captioned the photo: "tell ur bd [baby daddy] i said thx," followed by a laughter emoji.
According to the publication, the message was for Kylie, and it was about Travis.
The speculation comes after Kylie took to Twitter to speak out about her breakup from Travis.
"The internet makes everything 100 times more dramatic than what it really is. There was no “2am date with Tyga”. You see me drop two of my friends off at a studio that he happened to be at," she posted.
Adding in another Tweet: "Travis and i are on great terms and our main focus right now is Stormi! our friendship and our daughter is priority."
