Vince Vaughn dined at Buddakan with friends on Saturday night, but took a liking to the two older ladies from Chicago at the table next to his and ended up paying their bill. A spy told us, “Vince told the waiter he thought they were very sweet.” He also told the waiter he needed to rush dinner to get home to his kids. But as he was leaving the restaurant, a person outside recognized Vaughn “and told him he got fat,” said a source who added the star just laughed and said, “Thank you.” Across the restaurant, Joe Jonas had a low-key dinner with a friend. A young girl and her brother went up to their table and asked to have her picture taken with Joe, and he happily obliged.
