As reported in Life & Style, 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!
