Ashlee Simpson-Wentz wants out of her marriage. Citing "irreconcilable differences," the star filed for divorce from Pete Wentz in an L.A. court, TMZ reports.
After embarking on a romance in 2006, the singer and actress, 26, wed Fallout Boy rocker Wentz, 31, in May 2008, and welcomed son Bronx, 2, that fall.
In the filing, she asks for joint legal and primary physical custody of Bronx -- and seeks spousal and child support.
"They've been unhappy," an insider close to the couple tells UsMagazine.com. "They're living two separate lives."
Back in June 2009 -- just 13 months into their union -- Us Weekly reported serious friction and combative fights between the newlyweds. "They fight constantly," a source told Us at the time. "She is seriously considering leaving him....They're in different places."
