Britney's court drama begins....

Brit's assistant/cousin Alli Sims was served with papers by Kevin Federline's lawyer over the weekend.

Kevin and his attorney Mark Vincent Kaplan want to ask Sims all about Britney's lifestyle and parenting skills. Like, how often does she roll in front of her kids, hmmm?

Tabloids are reporting that her "lollipop" habit is all about absorbing heavy drugs. That would explain why she PASSES them around like a joint!

Sims was reportedly angry about being served. Oh well. Spill it bitch.
