The lawyer-turned reality, 26, became a hit with viewers of the rebooted ITV series this autumn.
Jordan walked away with £100,000 after being voted the winner of Big Brother 2023 in November.
But eagle-eyed fans have spotted a new feud a month after the TV house closed for business.
Jordan has unfollowed Trish Balusa on Instagram, with the outspoken star also removing him from her followers.
It comes despite the pair being extremely close during their time on the show.
Jordan’s now boyfriend and fellow housemate Henry Southan has also removed Trish from his social media.
ITV was forced to launch an investigation into Trish after historic tweets she had posted online resurfaced.
Despite deleting and apologising for her ‘racist and homophobic’ tweets, Trish wasn’t allowed attend the Big Brother finale with her co-stars.
In a statement at the time, Trish said: “I’m aware that some very concerning old tweets of mine have resurfaced and I would like to sincerely apologise for the harmful stereotypes I perpetuated and the pain I have cause to the marginalised communities and groups of people mentioned.
“There are no excuses for the ignorance that I showed and I am deeply disappointed, embarrassed and ashamed that I once made such comments.
“I have come a very long way since by educating myself and being educated by others on the impact and harm these views cause.
“It is part of the reason why I am so passionate about standing up for others and holding myself to a high standard of responsibility and accountability for my actions.
“I appreciate the support you’ve all given me on the show and I understand you feel disappointed.
“I know apologies can seem convenient in these circumstances but I mean it from the bottom of my heart; I am truly sorry.
“I hope it is possible for you to offer me grace and believe that people can change.
“I am committed to being the person I am now, the person you have known me as – someone who speaks up, stands for what they believe in and is always open to growth and accountability. Love Trish.”
