Michael Phelps Hours Before DUI Arrest Spotted Gambling At A Baltimore Casino

Before Michael Phelps was arrested for an DUI Tuesday, the swim champ had been gambling for 8 hours at a Baltimore casino, TMZ reported.

Casino sources claim that Phelps went to the Horseshoe Casino on Monday afternoon, found a private VIP gambling room stayed and played until about 1 am Tuesday morning.

According to the gossip site, Phelps was playing blackjack. There were little details on whether or not he played other card games during his 8 hour gambling. Sources are revealing that the former Olympian is a huge poker player.

But Phelps drinking inside of the casino is what probably led to his DUI arrest. His choice of drink was a cold beer. Phelps was pulled over around 1:40am, near the casino.

MStars News has also learned that Phelps is a regular at the Horseshoe casino, he was spotted playing poker there just last month.
