Federal prosecutors are asking a judge to allow them to read a statement from Stamos when two people are sentenced Friday for trying to extort $680,000 from him.
In July, Allison Coss and Scott Sippola were found guilty of conspiracy and using e-mail to threaten a person's reputation. They were accused of demanding money from Stamos in exchange for turning over embarrassing photos of him.
The FBI says there were no photos.
Stamos has known Coss for years after meeting her in Orlando, Fla., in 2004 when she was 17.
Stamos plays a dentist on Fox's hit musical "Glee."
