Pop star Christina Aguilera has filed for divorce just two days after announcing her marriage split, according to US reports.

The newly-single singer, who announced her separation from husband Jordan Bratman on Tuesday, reportedly cited “irreconcilable differences” in her divorce petition, which was filed in Los Angeles today.

According to the divorce papers, the couple – who wed in 2005 – have a prenuptial agreement in place.

The court petition reportedly requests that “earnings and accumulations of [Aguilera] before marriage, during marriage and from and after the date of separation” be regarded as separate property.

The date of their separation is given as 11 September.

Aguilera, 29, is also reportedly seeking joint physical and legal custody of their two-year-old son, Max.

"Although Jordan and I are separated, our commitment to our son Max remains as strong as ever,” Aguilera said when she announced the split on 12 October.
