Your assumptions about her may be correct….years and years ago she was on a really dodgy Welsh language programme on the S4C and there were a group of Welsh 20-somethings abroad (I think as holiday reps?). Anyway, one of the girls (not Alex) gave some unsuspecting holidaymaker head in front of everyone - literally walked up to a group of men, one of them was sat down minding his own business and went to town on him in front of everyone and Alex. It would definitely be seen as assault these days, and I remember Alex was one of the girls laughing and didn’t try to stop her friend at all. It’s definitely not on her IMDB page

She also puts on that accent these days and I can’t fathom how or why she’s promoted as much as she is

Her voice (and face) grate on me.
Another one to watch out for is the closeted Gethin. Allegedly Katherine Jenkins cheated on him.
