Ever wanted to make a cameo appearance on a favorite TV show?
Phelps, who has said he's a fan of the show, has an easy role to play -- himself.
Macht's character, Harvey Specter, is disappointed that he was unable to sign Phelps to his firm and Spencer's character "serves up some saucy dialogue" in an attempt to get him to change his mind, the paper reports. Phelps "plays it cool," USA Today says.
Phelps was giggly and starstruck when meeting Macht, USA Today reports.
"He kept on looking at me and giggling," Macht tells the paper of his first meeting with Phelps. But the two later hung out for most of the day.
But the world's most decorated Olympian had no problem delivering his lines.
"When it came to shooting, he turned out to be complete natural," Macht told USA Today. "We'd love to have him back."
Of course, it might have helped that Phelps only had four lines.
