It might have been the day after Easter, but Jennifer Aniston was still hard at work. While others enjoyed an extended break the actress took barely a day off from filming to enjoy the festival and was at work again early Monday morning. The long hours showed on Jennifers tired face and she looked less than perky as she walked down the street in New York, wiping her hair out her eyes.The day before many of Jennifers closest friends in Hollywood celebrated the season with an egg-hunt at the Malibu home of Hollywood executive Ronald Meyer. But while Courteney Cox, Kate Hudson, Steven Spielberg and Meryl Streep swapped gossip, Jennifer was in New York. The 40-year-old has thrown herself into her work since her split with on-off lover John Mayer. The couple had a rocky 11-month romance, with John writing on his Twitter page, just days later, 'this heart didnt come with instructions. The movie, which is due to hit cinemas next year, sees Aniston imitate her life in art, playing an unmarried 40-year-old woman called Kassie. -Daily Mail
