I think you may have confused her with someone else. There’s nothing on the net regarding her going lesbian; and if she joined that team I can’t picture them NOT shouting it from the mountain tops. That’s a woman one wants to be interested in you....
Her sexual preference has been a topic since the 1980s.
In Katarina's autobiography, Only With Passion, she clearly expresses a passion for males.
Heard it back a few years ago. I do know she is 48, never married has very close female business partner that she does a lot with, and has had a few very short male relationships. So who knows?
