Britney Spears‘ new found love of partying is not only worrying her record label but annoying potential producers too.

The Sun is reporting that Britney cancelled a meeting with Pharrell Williams about working together on her new album so she could stay in Hollywood with new friend Paris Hilton.

A source told the newspaper: “Pharrell takes this as a diss.”

Britney also cancelled a recording session in Miami with producer Scott Storch - first so she could go home to Louisiana for the first weekend after announcing her divorce from husband Kevin Federline but then because she claimed eldest son Sean had an ear infection. Britney was spotted out and about in Los Angeles every night over the long Thanksgiving weekend.
