Alli Sims, Britney’s assistant, and JR Totem, Britney’s music producer, were both served by Aaron Cohen of IMS Security with deposition subpoenas at 2:30 a.m. at a Hollywood Hills party. The deposition would force Alli to answer questions about everything from what Britney feeds the kids to what she’s like after partying. Us Magazine says,

A visibly upset Sims attempted to avoid being served, and she and Rotem began to argue with Cohen. But, as an eyewitness reports, Cohen was not deterred by Sims’ denials and was forced to throw the subpoena through an open car window as Sims and Rotem fled in a friend’s car. Spears was spotted leaving the the same party moments later and eventually joined Sims and Rotem at her Beverly Hills home.

Aaron Cohen sounds awesome. He served them by throwing the documents through an open car window while they were driving! That deserves four more exclamation points. He probably works for this IMS Secuirty too. Israeli anti-terrorist training security services? That’s insane. Aaron could have stuffed the deposition in Alli and Totem’s mouth if he wanted to, but he was probably feeling nice that day.

Britney Spears’ former assistant, Alli Sims, has given Kevin Federline detailed info on Britney’s erratic behavior. This will be used by Kevin to try and gain sole custody of their two kids, Sean and Jayden.

“Alli gave specific instances where Brit couldn’t handle having the kids. Kevin was angry at Britney for putting his kids in jeopardy and immediately phoned his lawyer to investigate the claims further. He couldn’t believe she had gotten so out of control.”

What could Kevin use against Britney. Hmm, well.

Spears was recently spotted driving with her younger son Jayden facing forward in his car seat, not backward as federal guidelines require. And earlier this month, he was photographed grabbing his mother’s cigarettes.

At this point in time, the guy known as K-Fed is actually the better choice for a parent. I’m surprised Britney hasn’t accidentally drowned her kids in the bathtub yet or pushed them to the ground trying to pry the last cookie from their weak little fingers. I can just imagine her screaming, “Dat’s muh cookie, Preston. Gimme!” while she whacks him with a rolled up magazine until he lets go.
