He won’t even let her leach cousin Alli Sims hang around anymore. Alli told Page Six:

“I have no idea when I’ll see [Britney] again. I miss her every day. When [Britney’s] dad gained control, he put some rules down . . . it’s just best for her to not communicate with a lot of people. My main concern is her being OK.”

I’m sure Alli misses the always available meds, knowing Brit’s ATM code and the never-ending supply of Frapps. I’m sure she thinks of this whenever she’s bussing tables at Waffle House.

Britney Spears’ longtime pal, Alli Sims, was served with legal papers concerning the custody battle between Spears and her ex-husband, Kevin Federline.

Leaving a hot party at a private home in the Hollywood Hills, Sims got served by Aaron Cohen of IMS-Security.

“Alli was really shocked and covered her face,” an observer tells People. “[She was] really distraught and said ‘Oh my God.’”

Britney Spears, who was also at the party, did not witness the serving of the papers, according to the observer.

The papers are a deposition subpoena sent by Kevin Federline’s lawyer, Mark Vincent Kaplan, compelling Sims to testify about Spears’s parenting skills.

Sims, who has known Spears since childhood and is regularly at her side partying in Los Angeles, recently told People:

“[Britney] is a wonderful mom and she is so hands-on… Britney loves those babies to death. And they adore her.”

Oh come on. The only thing she’s got her hands on is Matt Encinias.

On Wednesday, Kevin Federline filed for primary custody of the couple’s two sons, Sean Preston, 22 months, and Jayden James, 10 months.

A source close to Federline said recently that the would-be rapper has been worried about Spears’s behaviour and thinks she may be exposing the boys to “unnecessary risk.”
