After months of speculation and rumors, Tori Spelling has officially filed for divorce from her husband, Dean McDermott. The former "Beverly Hills, 90210" star submitted legal documents on Friday, listing irreconcilable differences as the reason for ending their marriage. Tori is requesting spousal support from Dean, as well as asking for sole physical custody of their five minor children with joint legal custody. She also wants Dean to cover her attorney's fees and is open to him having visitation rights. The couple, who tied the knot in 2006, did not have a prenuptial agreement, so the division of their assets and property will need to be determined as the divorce proceedings move forward. This marks the end of an era for Tori and Dean, whose marital struggles have been well-documented in recent months.
