We knew it was coming, but now it’s official… Christina Aguilera filed for divorce from husband Jordan Bratman today. Details on what caused the split along with photos of Xtina spending some QT at the Mr. Bones Pumpkin Patch with lil Max below:

Christina’s self tanner has her looking like one of those pumpkins!

Anyway, onto the dirty details of the divorce. We can’t say we’re surprised but Christina was allegedly creeping around. According TMZ reports:

Aguilera cited “irreconcilable differences” in her divorce petition obtained by TMZ, which was filed today. It’s an interesting twist, since sources tell us Christina is the one who cheated.

According to the divorce docs, there is a prenup. The divorce petition asks that “Earnings and accumulations of [Aguilera] before marriage, during marriage and from and after the date of separation” be considered separate property.

Aguilera, who is represented by disso-queen Laura Wasser, lists the date of separation as September 11, 2010.

The petition also seeks to terminate Bratman’s ability to get spousal support.

Aguilera is seeking joint physical and legal custody of their child, Max, who is 2.

Sources connected with the couple tell TMZ the marriage fell apart after Aguilera allegedly cheated on Bratman. Aguilera’s side refused comment.

Dang, Christina’s hubby has to deal with the public humiliation and give up on spousal support and a divorce settlement? It sounds like the poor guy is gonna get shafted in this divorce.
