Simone Biles to Larry Nassar Judge: 'You Are My Hero'

Simone Biles is giving the judge who signed Larry Nassar's "death warrant" a big, public thank you ... telling her, "YOU ARE MY HERO" for sentencing the ex-Team USA doc to 175 years in prison.

Simone -- who earlier this month revealed she was sexually assaulted by Nassar -- thanked judge Rosemarie Aquilina in a tweet just hours after Nassar learned his fate in a Michigan courtroom.

In the same message, she also gave a shout-out to all of Nassar's victims who gave impact statements in court "for being so brave and speaking like the queens that you are while looking at that monster."
