She was, but also did kid's shows and movies at the same time... Brazilians don't give a fuck. As a side note, I have a humorous anecdote about her. I was a mormon missionary in Chile where they can't pronounce the brazilian "x" or english "sh" sound, so they call Xuxa "Chucha" which also means cunt in spanish. So at one point, there was a wholesome mormon family watching a wholesome Xuxa movie for kids and I ignorantly started asking them if they liked Chucha and so on. I didn't understand why they all got red in the face until months later.
I remember Xuxa trying to make her American breakout in 1994 by broadcasting an english version of her children's show. She used to have little games for the kids and she would tell the child who won, "YOU ARE DA WEINER!!!" in her sultry Brazilian accent.
