According to The Sun, many of Laura Cognoi's friends have "lashed out" at the housemate over his kiss with Noirin under the duvet two days ago.
But his girlfriend has been much calmer, and wrote on the site: "I don't care tbh. I know I'm better than that, so I'm not even wasting my energy on making it into anything."
She later updated it again to suggest that she wasn't worrying about the situation.
"All my friends have been saying the same thing. Good job I've been doing yoga, coz I feel more amazing now than I've ever felt," she posted.
Siavash has been visibily worried about the situation and what it will mean on the outside world.
He last night told Noirin that he had "a lot of shit to sort out," but insisted that his feelings for her were strong.
When Sophie quizzed him about his girlfriend, he told her: "I was going out with a girl for a month but I said I was going to say 'girlfriend' so that nothing like this would happen," referring to house romances.
"But it's done," he continued, adding: "The public's going to dislike me for it."
