Along with lots of other celebs, Marlon Wayans attended the LA stop of Jay Z and Beyonce's On the Run tour.
Fortunately for us, Marlon didn't stop to consider that in such a star-studded environment there's a good chance that awkward chick next to you with the horrible dance moves might actually be famous in her own right.
Marlon posted the above photo to Twitter with the caption, "Man I got the MOST UNRHYTHMIC WHITE WOMAN dancing next to me at the jay and bay concert...this b-tch..."
The tweet has since gone viral, as it turns out that "unrhythmic white woman" is Australian pop star Delta Goodrem.
While most comedians might have immediately backpedaled and apologized, however, Wayans has stood his ground...in hilarious fashion.
Though she's most famous stateside for dating Nick Jonas, Goodrem has an army of obsessive fans Down Under, and they immediately to attack Wayans on Twitter.
"Let me start by saying suck it long, hard and til y'all mouths hurt to these sensitive ass people," Wayans responded. "Secondly, I ain't apologizing for a joke."
To her credit, Goodrem had a pretty solid response of her own.
She responded simply, "Had a blast last night," along with a YouTube link to the following classic Seinfeld scene:
Well played, Delta.
