Rivero, the daughter of Argentinian promoter Oswaldo Rivero, apparently turned the heads of many of those who went to view the training session with many unable to take their eyes off the very attractive 27 year old.

In fact at least 3 papers spoke more about her than the training session of Sosa which seemed to be over-shadowed his manager.
