Britney hits back at her abusive boyfriend

Washington, (ANI): For claims that she was physically abused by her boyfriend, Britney Spears has one message: 'Kiss My A--!"

The message was meant for ''Star Magazine, Radar Online, Jason Alexander and the rest of you liars" and read, “Ya'll can kiss my lily white southern Louisiana ass!" on Twitter, reports People.com.

The sentiment was prompted by a tabloid report that Spears, who turned 29 Thursday, was abused by boyfriend Jason Trawick. And the singer"s one-time husband, Jason Alexander, was the one who made the allegation.

In the report, Alexander says Spears told him Trawick "beat on me," and RadarOnline posted an audio clip of the alleged conversation between Alexander and Spears. The singer's representatives, however, deny the woman's voice on the tapes belongs to the pop star.
