Page Six reports that Britney Spears' cousin Alli Sims - who once acted as her personal assistant - is still banned from speaking to Brit... because of the rules father Jamie has enforced!

"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," explains Alli, who's currently working on her music in Nashville, Tennessee.

Will the former BFFs reunite? "I have no idea," Alli says. "I miss her every day." She also adds that "my main concern is her being OK."

Think this is really all Jamie Spears' doing? Or is it possible that this is partly Britney's wish as well?
