Just hours after Christina Aguilera was released from the West Hollywood Sheriff's station, ex-husband Jordan Bratman took 2-year-old son Max to a local park near his Santa Monica home.

As for whether Bratman will be able to keep Xtina's recently arrested beau Matthew Rutler from seeing his son, custody specialist Michael Kelly tells us:

    "Courts do not ban the birth person's significant other from seeing the child. However, the other parent can order 'no alcohol or drugs for 24 hours' before the parent in question or her boyfriend sees the child."

Video coming soon of Jordan and Max.
