HOLLYWOOD - Britney Spears' rehired assistant, Ally Sims, was served with court papers early on Sunday morning at a house party.

Life & Style magazine reports Sims, who is also Spears' cousin, was "absolutely angry" by the intrusion, initiated by the lawyer representing the pop star's ex-husband Kevin Federline in the couple's upcoming custody battle.

The publication claims the legal documents call for Sims to reveal what she knows about Spears' parenting skills and questions about the "Toxic" singer's drinking and partying habits.

Just last month, it was believed Sims was helping the Federline camp as they prepared for a custody battle after quitting Spears' employ over fears for the singer's sons.

Sims has since slammed those reports, insisting her cousin is a great mother.
