Miley Cyrus has focused on their careers and, between sexy video , promotions and controversy , does not have much time to devote to his personal life. Perhaps for this reason that, until now, nobody has felt the wind of a marital crisis between Billy Ray and Tish Cyrus, her parents. The couple decided to divorce after 17 years of marriage.The two announced yesterday, by mutual agreement, this decision in People magazine . Unlike so many divorces taking place in that Hollywood, the last of which involved Christina Aguilera and husband, in this case there would be no betrayals or stories on the edge of the law behind this separation. Simply, after many years, the couple admitted to having lost the link to the past.
