It may have been a lovely cruise for Outkast rapper Big Boi, but disembarking in Miami got ugly Sunday. Border patrol dogs busted the "Hey Ya" singer as he got off the ship, and he was charged with three counts of possession of a controlled substance and one count of possession of drug paraphernalia. TMZ reports that the controlled substances were MDMA, aka ecstasy, in pill and powder form. The other substance was Viagra, for which (not so, apparently) Big Boi did not have a prescription. Boi, aka Antwan Patton, was booked into Miami-Dade jail at 1:35 p.m. Sunday and is being held on $16,000 bail. Sounds like someone picked up some special souvenirs on vacation.
