Katie Holmes visited an NYC gym this morning then later left her apartment in the company of Suri and a famous mouse, Angelina Ballerina. Suri loves exploring the city with her dolls, and this time Angelina joined the pair on their daily activities. The girls are back in the Big Apple following a recent visit to Louisiana, where Tom Cruise is shooting his latest project, Oblivion. Few details about his futuristic drama have been released, but another high-profile project starring Tom is getting lots of press. Recent reports suggest Tom is close to signing up for a Top Gun sequel, though no word on when and where production would begin. Tom's 2012 calendar is already packed with projects, and he'll likely have to hit the road prior to June's Rock of Ages and the holiday release of One Shot.
