AURORA | Missy Franklin is growing up.

The star of the London Olympics turned 18 last week. She graduates from high school Monday. She even went to the bank the other day, putting the accounts in her name to get ready for life as an adult.

She says, “It’s crazy. I don’t know where the time went.”

After Franklin won four gold medals and five medals overall in London, she returned for her senior year at Regis Jesuit High School in suburban Denver.

Franklin says it’s been an “amazing” year. She met everyone from Justin Bieber to Prince Harry, but also got a chance to relish many of the normal activities of a high school senior — from attending the prom to helping her school win the state swimming championship.
