Washington, Mar 4 : Britney Spears' boyfriend Jason Trawick hates her music, sources say.

During socialite Paris Hilton's recent birthday bash, the talent agent apparently voiced his displeasure when the deejay played Spears'' track `Toxic.'

"Jason arrived with a male friend, but was definitely enjoying himself until DJ Mr. Best, threw on Britney Spears'' song `Toxic,'" Fox News quoted a source as saying.

The insider added: "When the song came on the first thing out of Jason's mouth was `OMG I hate this song!' His friends all laughed and continued to talk, but he interrupted them by saying, `I'm sorry, I can't hear what you're saying over her voice.' He wasn't laughing." (ANI)
