Christina Aguilera filed for divorce from her husband of five years Thursday, two days after announcing the couple had separated.
The "Beautiful" singer cited irreconcilable differences with her husband, music executive Jordan Bratman, The Associated Press reports.
Court documents show the couple has a prenuptial agreement, although Aguilera is seeking a judge's ruling awarding her rights to all her earnings.
Aguilera, 29, is seeking joint custody of the couple's 2-year-old son. She announced on Tuesday that she and Bratman had separated and that the couple's commitment to their son "remains as strong as ever." She did not issue a statement regarding the divorce filing, and a phone message left for Bratman was not immediately returned.
The pair were married in November 2005 and separated on Sept. 11, the court filing states.
The divorce was first reported by celebrity website TMZ.
