Pop princess Britney Spears has been enjoying herself lately but is the constant partying taking a toll on her career? As we mentioned earlier today, Britney’s record company is worried about her status and so is her music producer.

According to the Miami Herald , Britney was supposed to be at the Marlin Hotel today, recording with Pharrell Williams. Williams had some cupcakes delivered to the recording studio as a little gift to Britney, who has been ditching her recording sessions in favor of partying with her sidekick.

According to reports, Britney has dissed the famed producer twice and we hear he isn’t too happy about it. What do you guys think, is Britney jeopardizing her career or is all this publicity going to help her regain her fame?

UPDATE:We just got word that Britney Spears is confirmed to host a New Year's Eve party at Pure Nightclub in Las Vegas.
