It looks like Pia Toscano has decided that her old boyfriend doesn’t fit in with her new C-list lifestyle, and she’s climbing the social ladder while trying out new candidates. Â Carlos Nunez, Toscano’s boyfriend of four years, has been left wondering what happened after Toscano started going on dates with Mark Ballas of Dancing with the Stars. Â Toscano did not break up with Nunez first – she simply started dating Ballas and stopped returning her boyfriend’s calls. Â When asked if they were in a relationship, Ballas simply said that they are having a great time and he has no complaints. Â Poor Carlos, he deserves better than that. Â The least Pia could have done is told him it was over.
