I heard (keyword - "heard") that Pierre dumped Joanna when he got the opportunity to dance with Julia Gorchakova (a champion with her husband, Bob Powers). Again, that's just what I've heard.
I thought Joanna looked much better this year. I think she is well-matched with Jose and he showed her off nicely. And, she looked much slimmer - I don't know if it was her costuming or her actual body, but she looked great. I did like their Black & White number last year. That was pretty awesome. Pierre is definitely high energy!!
If what I heard is true, that must've been a great feeling to come in 1st over her former partner, but who knows?!? You know how these dance rumors go....
