It looks like those knees are doing just fine!!
Following the "Your Most Memorable Year" theme, Amber decided to go back to the beginning of career on Glee in 2009, and the judges praised her waving her diva flag proudly!
However, Len Goodman proved to be a bit of stickler as he returned to his spot at the judges table and only gave them a 7, saying their dance wasn't a traditional foxtrot!
The other judges didn't seem to mind as they still earned a 9 and perfect 10 to bring their total score to 26, but we can't help but wonder how much higher that would have been if Julianne Hough would have still been in Len's seat!!
Ch-ch-check out their Glee-ful foxtrot (above)!
