Britney Spears: "Kiss My Lily White Southern Louisiana Ass"

"Ok, off on a romantic weekend with Jason for my birthday. xoxo Brit," the now 29-year-old singer tweeted right before flipping the verbal bird at Star, Radar and her incidental onetime husband.

RadarOnline posted an audio recording of a purported conversation between Britney and Alexander in which he asks if she and Trawick are engaged and a female voice replies, "Was that before or after he beat me?"

Star, which shares a parent company with Radar, simultaneously ran a cover story announcing, "Jason Beat Me Up."

"What StarMagazine & RadarOnline did is disgraceful and irresponsible! We will not take this sitting down," tweeted Britney's manager, Larry Rudolph, using his client's Twitter account.

Added Rudolph colleague Adam Leber: "Radar Online clearly has no idea what Britney Spears sounds like. These recordings are a joke."
