Miley Cyrus tough exterior seemed to break down as she performed to a sold out crowd, wearing a skimpy white corset with barely there matching white shorts and high heel Converse shoes.

Miley is reported to be having a hard time with her breakup with her on-again off-again fiance because he has moved on so quickly and so publicly.  He was spotted kissing his new love interest, Elza Gonzales, just one day after he and Miley officially announced their split.  He looked to be enamored with his new Latin lover and held her close as they gave each other a passionate kiss inside Liam's underground garage at his apartment complex.

Actress, Elza Gonzales, is relatively unknown in the United States but she is very famous in her native country of Mexico, where she has been a fixture in telenovelas since she was a teen.
