I disagree. Here you go they are both on video from 2015, it started affair about Kowalkiewcz talking some stupid shit about some people from mma comminity, Jedrzejczyk saying something at the end of video:
Here you got video from 2016:
Bad blood af.
So how many years she crapped on Karolina? She didn't exaggerated here. It's called lie. And it should be pointed out.
She is actually mess in this interview talking like she doesn't like Jedrzejczyk, and want Rose to win, but at the end she wishes Joanna all the best.
Prior UFC 205, her only loss was Jedrzejczyk in amataur competition, and she was beaten as pro first time by Jedrzejczyk, so yes she is not biased.
