She is obviously team Jacob because she wants better for Bella than for her to throw her life away to be a vampire. Then again, she despises Jacob and wants anything but for him to be happy. I believe she would rather Bella just end up with Mike or some other human. That way Bella stays human, and Jacob will be sad. But if you think in future terms, Bella and Edward is the reason she got to be with Renesmee, therefore, she would probably let Bella be a vampire so Rosalie can selfishly have Nessie. :) But at the end of the day, I think she'll have to go with team Emmett.
Whew- that's a lot. :)
OH! That too!!! :D I AGREE!
Team Edward. But it would be very funny if she was Team Jacob! :D
