Hollywood star Sharon Stone has lost physical custody of 8-year-old son Roan to former husband Phil Bronstein.

Entertainment Tonight is reporting that the ongoing custody battle between former spouses Sharon Stone and Phil Bronstein has come to a sad end for the Hollywood actress.

Court documents detailing a Sept. 12 custody hearing show that it was decided that Phil Bronstein “shall have permanent sole physical custody of child.”

“Court finds that Respondent (Sharon Stone) failed to meet her burden of proof and denies Respondent's (Sharon Stone's) request for modification of custody,” the papers read, as quoted by ET.

The order is permanent unless there is a change of circumstances. Sharon Stone will not be completely deprived of her son’s companionship, as her visitation rights, as well as holiday and vacation rights remain in place.

Sharon Stone married newspaper executive Phil Bronstein in 1998; the union ended in divorce in early 2004. They had in the meantime adopted Roan, now 8. Following the divorce, Stone adopted two more children, son Laird, in 2005, and son Quinn in 2006. The two younger boys are now 4 and 2, respectively.

According to Entertainment Tonight, custody of son Roan was very different a year ago, as court papers dating from Oct. 2007 show that the former spouses had “joint legal and physical custody” at that time.

The Associated Press adds that the judge ruled that Bronstein’s home is more stable and structured. The parents much agree upon tutoring activities they wish to enroll Roan in and the child is to have Sharon Stone’s telephone number programmed into his cell and home telephones.
