This is Brazilian fitness star Bianca Ruiva.
I could not find out much about her other than she is a fitness model and she posed with the wildly popular Eva Andressa (see below).
One description I read said, "Bianca ruiva redhead muscle brazil" and that about sums it up.
You can follow Bianca on her facebook page here:
