has filed for divorce from estranged husband Nick Lachey
. The sexy star started legal proceedings on Friday citing "irreconcilable differences" as the reason for the pair's split in November.
According to court papers, Jessica has requested that Nick is not awarded spousal support after the pair separate and is legally reverting back to her maiden name after changing her name to Jessica Lachey after their marriage.
The blonde singer-turned-actress has hired divorce attorney to the stars Robert Kaufman to represent her, while Nick has enlisted the help of lawyer Laura Wasser - who also has experience of representing celebrities. The divorce between the pair - who starred in MTV reality show Newlyweds
together after tying the knot - is set to be problematic because they never signed a pre-nuptial agreement before getting wed in October 2002. At the time, Nick's earnings were higher than Jessica's because he was earning a fortune as a member of successful boy band 98 Degrees
. However, during their marriage Jessica's career has gone from strength to strength with the blonde beauty earning a staggering $35 million in 2004 alone.
Under California all money amassed during a marriage must be split 50-50 if there is no pre-nuptial agreement in place.
