Paris, Prince and Blanket Jackson  were all spotted at The Grove yesterday -- and while Paris (left) sported a shirt with MJ's pic on the front and Blanket (right) wore an Ed Hardy tee (MJ and Christian Audigier were pals) ... it's unclear if Prince's shirt (middle) has any connection to the King of Pop.


Where's the red zippered leather jacket and the "Billie Jean" tux?
