Only time will tell if a casino career is in the cards for Jessica Simpson and fiancé Eric Johnson's baby boy, whom they welcomed June 30. His middle name, however, honors Johnson's Swedish grandfather, a rep tells PEOPLE. Ace's sister, Maxwell Drew, 14 months, also keeps it in the family: Maxwell is Johnson's middle name, while Drew is Simpson's mother Tina's maiden name.
