Will Brit Lose Her Children?

Britney Spears may have torpedoed herself in her custody battle.

L.A. County Commissioner Scott Gordon laid down the law for Britney, mandating that she and K-Fed be drug and alcohol-free while they have physical custody of the children.

Depending on what Brit was under the influence of, K-Daddy's lawyer Mark Vincent Kaplan could go back into the court and immediately ask the judge to strip Britney of visitation rights.
