23-time Olympic gold medalist Michael Phelps is back from the Rio Olympics and stopped by Sports Illustrated this week to answer questions from fans on Facebook Live.
During the Facebook Live, someone asked about his son Boomer who became a star during the Olympics.
One person asked if Boomer will be a Trojan, because his mother went to USC.
As a response, Phelps said, "Boomer's going to Michigan. Go Blue."
Phelps attended U-M after the 2004 Olympics and has trained at the university's facilities.
