The contemporary dancers, both 18, were sent home from the Fox competition during the first audience-determined elimination of the season last night.
Their departure means that this season's top eight finalists have now been revealed.
Speaking to E! News following the show, judge Mary Murphy said: "We were kind of shocked that America didn't take to Nathan the first few weeks, because he's an amazing dancer.
"When you tell the general public that you get everything you want, that's really not endearing and it really hurt him. You have to be not only a smart dancer, but smart in how you present yourself."
Ashleigh Di Lello, Ryan Di Lello, Russell Ferguson, Mollee Gray, Jakob Karr, Kathryn McCormick, Legacy Perez and Ellenore Scott will continue to compete for the title of America's Favourite Dancer next Tuesday.
Next week's results show will also feature a performance from American Idol winner Kris Allen and Wonder Girls.
