Davies dated Cetinay after they met on, and won, last year’s series before splitting earlier this year.
Despite Davies moving on with James Hawkins, she doesn’t seem too keen on her ex striking up a relationship with Rae-Knight.
The pair were seen flirting on Sunday’s spin-off show Aftersun, leading Davies to take back her previous comments about Rae-Knight being “adorable”.
Davies retweeted her post alongside the new caption: “Well I take that back.” She has since deleted the tweet.
Rae-Knight was grilled on her relationship with Cetinay by Holly Willoughby on This Morning.
Willoughby said: “The person who did seem quite keen to spend some time with you was last year's winner Kem.
“He was quite flirty with you. He was saying if he’d have been in there with you he would have coupled up with you. You’re his type.”
Phillip Schofield asked if they had exchanged numbers to which Willoughby shouted “that’s a yes” after Rae-Knight hesitated.
