Britney Spears are making waves on Twitter and Facebook today as she celebrates her 29th birthday. Spears did not mince words in slamming entertainment outfits which reported that she was physically abused by her boyfriend Jason Trawick.

"Star Magazine, Radar Online, Jason Alexander and the rest of you liars, Ya'll can kiss my lily white southern Louisiana ass!," wrote Spears on her Twitter account.

The pop singer also revealed that she will be in a "romantic weekend" with Trawick, while at the same time, telling fans that she is almost done with her new album which comes out on March next year. The star also thank fans for the wishes and greeting she received today for her 29th birthday.

"Just wanted to thank all of you for the amazing birthday wishes you guys have been sending all day," wrote Spears in her Facebook page.

"My fans mean the world to me & waking up to all of your wishes really made me smile, so here's something that I hope will make you smile..."

Spears figured in a controversy this week, when several entertainment outfits such as Star Magazine and RadarOnline run a report on the alleged physical abuse that Britney received from Jason Trawick. The allegations were made by Spear's former husband Jason Alexander, with RadarOnline posting an audio clip featuring a voice of a woman attributed to Spears. Spear's team had already issued a denial, calling the reports false. In a statement, the camp of the pop singer said they will pursue legal action on the matter.
