LOS ANGELES: Pop star Christina Aguilera on Thursday filed divorce papers seeking to end her five-year marriage to music executive Jordan Bratman.

Citing irreconcilable differences, Aguilera filed papers in Los Angeles Superior Court just two days after confirming that she and Bratman had separated earlier this year.

The couple have a two year-old son, Max, and are asking for joint custody, according to the court documents posted on celebrity website TMZ.com.

Us Weekly magazine reported on Tuesday that the “Beautiful” US singer and her husband had split up a few months ago but had not made a decision on divorce.

The website quoted an unidentified source as saying that the pair had become “more like friends than husband and wife.” Aguilera's divorce papers said she and Bratman separated in early September.

Aguilera, who had a huge early hit with “Genie in a Bottle”, and Bratman married in November 2005. They met in 2002 while Jordan was working for Aguilera's music management company.

A former Disney teen performer, Aguilera is due to star in her first feature film, the upcoming musical “Burlesque”. -Reuters
