At Sunday's ACM Awards show Ashton Kutcher dressed in cowboy wear and sang George Strait's "I Cross My Heart" off key.

Now ... a few country artists are upset over Ashton's stunt. They think that he was making fun of country.

Miranda Lambert tweeted, "Was Ashton Kutcher making fun of country or is it just me?"

Justin Moore tweeted, "I don't care for people making a mockery of the way country artists dress."

What do you think?

Was Ashton just being funny or was he making fun of country?
