Britney Gets Served

Model mama Brit-Brit's drama has now spread to her assistant/cousin Alli Sims!

Britney's cousin Alli Sims was served with papers by Kevin Federline's lawyer in the dead of night.

Why does K-Fed want to talk to Alli? It seems he and his lawyer Mark Vincent Kaplan want to grill her about Britney's lifestyle and parenting skills - including how much she boozes it up in front of the kids.

Alli was reportedly super steamed by the "serving." Court's in session, y'all!
