On March 1, Epic Records will release Jennifer Lopez's new album Rebirth. The collection is described as "old school meets new school." Guests include Fat Joe, Fabolous and Jennifer's husband, Latin pop star Marc Anthony. The album's first single, "Get Right," recently climbed to Number One on the U.K. charts. In other news, Lopez recently cancelled a trip to London, where she was to attend the European premiere of her latest film "Shall We Dance." She was also scheduled to promote her new album there for several weeks. The cancellation sparked rumors that she's pregnant, but a spokesperson for Lopez said it was simply a case of the flu.
