Britney Spears’ cousin and personal assistant Alli Sims is blasting Sarah Silverman’s remarks about Brit’s children at the 2007 MTV Video Music Awards-labeling the comedienne “mean.”

Sarah created a controversy at Sunday’s ceremony when she said this:

“Have you seen Britney’s kids? Oh my god, they are the most adorable mistakes you will ever see. They are as cute as the hairless vagina they came out of.”

When confronted by photographers outside a grocery store -Alli told the paps: “She’s mean…mean,”

“She’ll have kids one day and she won’t appreciate that crap.”
