Gladys Knight may be a Rock and Roll Hall of Fame inductee, but the R&B diva just couldn't get her act together during Dancing With the Stars' rock-themed performance round Monday.

Performing a tango to Queen's "Bohemian Rhapsody" with pro partner Tristan McManus, Knight, 67, earned a disappointing 20 out of 30 points, making her the night's lowest-scoring star.

Though head judge Len Goodman applauded Knight for keeping up with difficult music and choreography, he later went on to criticize her posture. Bruno Tonioli agreed with Goodman, arguing that Knight's routing "lacked impact."

The View's Sherri Shepherd didn't fare too much better than Knight Monday, earning 21/30 for her tango with Val Chmerkovskiy. "It was good, but what was lacking was your usual exuberance," argued Inaba. "Your face was expressionless. I felt like there wasn't any sparkle."

Three celebs earned a score of 22/30 Monday night: William Levy, Jaleel White and Melissa Gilbert, who was treated for a mild concussion and whiplash she suffered after performing the paso doble with Maksim Chmerkovskiy.
