Christina Aguilera & Ex-Husband — Divorce Is a Beach

Christina Aguilera and her ex-husband Jordan Bratman have called a truce — at least temporarily — and got together for a beach playdate with their 5-year-old son this weekend.

It”s pretty commendable that the Xtina and Jordan played nice — considering they went through a pretty nasty divorce … with Jordan initially refusing to move out of the family home and forcing Aguilera to move into a hotel.

But this weekend, it was all smiles in Venice Beach … where J & C came together to escort little Max to a birthday party.

As for Christina”s boyfriend Matt Rutler — he wasn”t a part of the festivities.
