Star magazine and Radar Online are sticking behind their story that Britney Spears called ex-husband Jason Alexander to complain about current flame Jason Trawick -- and Brit sent them a very public message on Thursday.

Her Twitter page offered up this little gem: “PS--Star Magazine, Radar Online, Jason Alexander and the rest of you liars, Ya'll can kiss my lily white southern Louisiana ass!" (First things first: we want the Twitter page checked for accuracy. No southerner should ever spell y'all incorrectly.)

Earlier this week, Radar Online released an audio clip of a woman whom they say is Britney Spears, speaking to Brit’s two-day hubby Jason Alexander. The Spears camp categorically denies all claims made by the magazine, the gossip site and Jason Alexander, but Star is completely supporting their story (naturally).

"Star magazine stands by its story that Britney Spears told her ex-husband, Jason Alexander, that her boyfriend, Jason Trawick, beat her," Star said in a statement. "In a taped phone conversation lasting for more than one hour, Ms. Spears can be heard repeatedly telling Mr. Alexander how Mr. Trawick ‘went crazy’ and hit her, giving her a black eye."

According to the mag, Alexander took a polygraph exam to back up his claims - and passed. The magazine’s prepared statement adds, “Moreover, there is information in the tape, which Star may reveal at a later date, that would be known only by Ms. Spears."

Meanwhile, Radar Online has released a third audio clip, in which “Britney” says that Trawick started beating on her so she “went and had an abortion.”
