A soon-to-be-single Shaquille O'Neal was seen scouting some pricey South Beach bachelor pads last week, looking for a new place to hang his head in the wake of his split up with Shaunie. After house hunting high rises, Shaq hit Flamingo Park where he shot hoops with the locals . . . Over on Ocean Drive, producer Jerry Bruckheimer shut down an entire block to traffic, not for a movie, but for his own personal production----a huge crane was installing a new pool in his posh penthouse. We can't even stop traffic to hail a cab. Must be nice.
