Madonna and trainer Tracy Anderson in happier days.

We learned via Social Workout that Madonna is adding the ultimate home gym to her new Upper East Side mansion. She’s literally adding a floor to the $40 million townhouse on 81st Street that she purchased last year. Guess the 13-bedroom, 9-fireplace house just didn’t have ample room for a home gym. And we guess that when Madonna thinks “home gym” she’s not dreaming about an Elliptical, some free weights, and a bag full of resistance bands, like we are.

No doubt Madge is planning the second coming of Reebok Sports Club/NY with lots of futuristic fitness stuff and pool boys galore. And we wonder if she’s hired a new trainer now that she and Tracy Anderson aren’t pumping 3-pound weights together. Anyone know?
