Amy (Duggar) King has thick skin about Josh Duggar jokes.

Brad Paisley made a joke Wednesday night about the disgraced former 19 Kids and Counting star's infidelity, after his connection to Ashley Madison, a website that caters to people looking to have an affair, surfaced – and one of Josh’s extended family members had a laugh about it.

"Whoa!!'@BradPaisley wasn't expecting THAT," Amy tweeted. "Laughing hysterically."

The bit went like this:

"'Have you heard that duet Blake [Shelton] did with Ashley Madison?" Brad asked during the CMA Awards, to which Carrie Underwood answered, "'No, no, that was Ashley Monroe."

"Have I been going to the wrong site? We don't have to be lonely at farmersonly.com," Brad joked in return. "Bored with your wife? And your sister, too? Your cheating side will tell on you, Josh Duggar."
