I've never seen those bts before!
Where are they from?
I doubt if they were together they'd actually make it public before the show ends anyway, it'd cause too much drama. I remember watching an interview with Sophia Bush where she was speaking about her relationship with Chad Michael Murray and how concerned the producers were about it affecting their work. And after how horribly that turned out I doubt too many more will be so out there, especially when so much of the show relies on their chemistry. Any bts drama could seriously impact that and there's no way any TV network would want that.
