Franklin isn't ready to become a professional athlete yet. She'll swim in the world championships in Barcelona this summer before heading to the University of California at Berkeley in the fall.
Franklin plans to swim for her college team the next two years, finally turning pro after the 2015 NCAA championships. That will give her a chance to earn some of the big endorsement dollars leading into the Rio Olympics.
She celebrated her 18th birthday earlier this month. She attended a reception that night with Britain's Prince Harry, who joined the crowd in singing "Happy Birthday" to her.
