What will Demi Moore say about this?

Ashton Kutcher really, really put his foot his put in his mouth via Twitter on Wednesday.

The fidelity-challenged actor, 33, was savaged by his followers after standing up for Penn State football coach Joe Paterno, who was fired amidst a huge child-abuse sex scandal.

Paterno, 84, was forced to end his 46-year career after former assistant coach Jerry Sandusky was charged over the weekend on 40 counts of sexual abuse of children. Paterno apparently failed to act and contact the authorities when alerted about Sandusky's misconduct nearly a decade ago.

Kutcher's take? "How dare you fire Jo Pa?" he tweeted. "Insult #noclass as a hawkeye fan I find it in poor taste."

Kutcher's 8.3 million followers didn't exactly approve. Demi Moore's husband was quickly slammed as an "idiot" and "ignorant.

"F— you," one fan sniped. "He covered up child rape you sick, geriatric f—."

"With 8 million followers, you MAY want to reserve your opinions until you know the whole story," added another outraged fan.

Adding insult to injury, Kutcher and Moore, 48, have an eponymous foundation that fights child sex slavery worldwide.

Taking down his initial tweet, Kutcher finally explained his confusion.

"Heard Joe was fired, fully recant previous tweet! Didn't have full story. #admitwhenYoumakemistakes…"This is an insane story, I just heard paterno was fired, getting the rest of the story now… Wow" and "As an advocate in the fight against child sexual exploitation, I could not be more remorseful for all involved in the Penn St. case"
