Treating herself to some much-needed time off,  Jennifer Aniston was spotted sunbathing off of the beach in Mexico yesterday (November 12). The former “Friends” hottie looked to be enjoying her relaxing afternoon, though she seemed nervous about the nearby paparazzi as she fidgeted with her bikini top with numerous security staffers on-hand. In related news, Star magazine is reporting that Miss Aniston has been known to play mind games with her ex-husband Brad Pitt’s lady Angelina Jolie. A source told the tabloid, “Jen and Angie despise each other and take great pleasure in seeing each other squirm.  Among the tricks Angie plays are finding from designers what dress Jennifer wants to wear on the red carpet then going out to grab it for herself. Jen likes to make late night calls to Brad when he’s in France conveniently forgetting the time difference so she will wake her nemesis in the early hours.
