Lady Gaga didn’t keep much of a poker face at the tables in the high-limit area of the Borgata in Atlantic City after her concert at Boardwalk Hall. Though she didn’t win big, “she looked happy playing around with friends and family,” said an onlooker. Gaga graciously thanked her fans for coming: “I know the economy really sucks right now, and you spent your money on hanging out with me on the Fourth of July, so I thank you.” Gaga plays Madison Square Garden this week.
