Her ivory-tickling fingers have undoubtedly got the rhythm, but Delta Goodrem's been busting "unrhythmic" dance moves according to Marlon Wayans.
The American comedian has dissed the Australian songstress in a humorous Instagram selfie he took while apparently trying to enjoy a Beyonce and Jay Z concert during their The Run tour in Los Angeles.
The snap, which has gone viral, shows Wayans with his eyes awkwardly raised as he watches a seemingly oblivious Goodrem groove along to the music.
"Man I got the most UNRHYTHMIC WHITE WOMAN dancing next to me at the jay and bay concert... This b**** dancing to AC/DC," he captioned the picture.
