The whole thing was captured for ‘To Catch a Cheater’, with Sofia contacting the Youtube show after she wanted to put her stepdad to the test.

“Sofia hit us up on Facebook, wanting to setup her step father, to see if he'd cheat on her mother or not,” the description reads. “They've been together for 10 years, and married 2.

“She said she's always had her suspicions about him because he would be a heavy flirt with her since they've met. She tried to brush it off as him being friendly, but always felt strange about it.”

In footage that was posted last year but has gone viral again, Sofia’s stepdad can be seen making small talk with a young woman about sports, before she asks for his phone number.

He’s more than happy to give it to the girl, who looks about half his age, and can be heard denying he has a partner.

Sofia can’t hide her shock as she watches the footage, and claims it’ll destroy her mum – but she’s determined to tell her the truth.

“This would ruin everything. I don’t even think she would want to find someone else after this. She would never trust anyone,” says Sofia.

This is going to crush my mum… That is cheating,” she says. “I would separate from him.”
