There will be no romantic reunion — Jessica Simpson filed for divorce Friday from Nick Lachey.
The couple had jointly announced their separation Nov. 23 following months of rumors that their tabloid-friendly relationship had soured.
Simpson cited irreconcilable differences in a divorce petition filed in Los Angeles Superior Court.
Calls for comment to their publicists after the court filing were not returned.
Simpson, 25, and Lachey, 32, wed in October 2002 and went on to star in their own MTV reality show, "Newlyweds." The pair also hosted a 2004 television special, "The Nick & Jessica Variety Hour."
Simpson's star power skyrocketed after her marriage. Her 2004 album, "In This Skin," went platinum, and she released a Christmas album last year titled, "ReJoyce The Christmas Album." She made her big-screen debut this year, playing Daisy Duke in "The Dukes of Hazzard."
Lachey gained fame as a member of the boy band 98 Degrees. He released his solo album "SoulO" in 2003. Lachey also appeared in episodes of "Charmed" on the WB and is slated to star in a pilot for the network in 2006.
In a statement released following their split last month, Simpson and Lachey said that "after three years of marriage, and careful thought and consideration, we have decided to part ways."
