People magazine reported Friday that, according to court records, music executive Jay Faires cited irreconcilable differences in filing for divorce from Matenopoulos.
In his legal filing, Faires said the couple's property rights had yet to be determined and asked that Matenopoulos not receive spousal support.
Wednesday's documents detailed the couple's marriage in 2003 and their official separation this March, People said.
The 33-year-old E! host, who has been nominated for two Emmy Awards during her career, had no children with Faires during their marriage.
