Ben Jardine has suggested Roxanne Pallett's fiancé should "re-evaluate" their relationship.
The 'Married At First Sight' star and the 35-year-old actress - who is engaged to Lee Walton - were seen flirting in the 'Celebrity Big Brother' house, and Ben believes Lee should look into their romance.
When asked on talkRADIO if he feels bad that the former 'Emmerdale' star and Lee are still together, he said: "No - I don't want to be that guy. At the same time he needs to do what I had to do after 13 years, he needs to re-evaluate the situation."
Ben, 36 - who is currently divorcing wife Stephanie after they met on the dating show - has promised to never see Roxanne again, and admits he "had to stop [himself]" from flirting with her because she has a partner.
He added: "I ain't going to be that guy. I'll be honest, single? Yes that would've happened.
"But I had to stop myself and I was the one who walked away from that. All I can say is eyes don't lie.
"I know I need to get myself back to Specsavers but eyes don't lie and if someone's there for ten seconds they ain't there for their health."
Ben was evicted from the reality TV show last month, and went on to suggest Roxanne is a "lovely girl", but admitted he felt "a little bit of a mug".
He said after leaving the house: "All I'll say is she's a lovely girl, she does what she does.
"I do feel a little bit of a mug sat here right now ... she was a comfort blanket for me ... I think she's a lovely girl, that's all I can say ... I do feel a bit upset, played."
Roxanne has since been forced to apologise after falsely accusing former 'Coronation Street' actor Ryan Thomas of punching her in the reality TV show digs.
The former 'Waterloo Road' star said sorry in a TV interview and admitted she had "got it wrong".
