Britney Spears' manager has slammed reports that work on the pop star's comeback album has been halted because record company executives are unhappy with her songs so far. The TOXIC star recently spent time in a New York City recording studio laying down five new tracks, but executives were reportedly less than impressed with her efforts. According to New York Post columnist CINDY ADAMS, the project has come to an abrupt stop midway through the recording process because bosses are trying to decide whether to redo the tracks or to drop the project entirely. Adams claims executives are also worried about the singer's hard partying ways and recent negative publicity saying, "Jive fears she's alienating her fan base. "Jive is not in sync with the five tracks Brit delivered." Spears' manager LARRY RUDOLPH slams the claims, telling Adams, "I don't know where your information came from, but I can only tell you we're in the middle of recording an album." Rudolph has also dismissed reports Spears has checked into Arizona rehabilitation facility Sanctuary for some much-needed rest and relaxation. The pop star is said to have checked in on New Year's Day (01JAN07) after reportedly collapsing at the end of a New Year's Eve party at Las Vegas' Pure nightclub.
