The conversation started when Mario asked Corin whether she had been straight before she was with her current girlfriend.
"Oh yeah," she told him. "I was just really attracted to Rachel the same way I would be attracted to a guy."
Corin then asked Mario how he felt now that all his family and friends would know that he was gay.
"Well at the end of the day, this is why I wanted to do Big Brother," Mario said.
Corin agreed, telling him that she felt like a weight had been lifted off her shoulders. She added that she had been very nervous when coming out to her mum, but that she had been 'like her backbone' during the hard times.
