"I feel a tremendous amount of pressure," she said while struggling to master the week's movie score theme. "Has anyone ever quit the show?"
"I am going to have a breakdown. I just can't do it," Lake, 43, complained. "It's just very confusing for me. I am not getting it. I want to quit. Like I totally want to quit -- and I am not a quitter."
Despite her initial frustrations, Lake's determination paid off. Her Psycho tango impressed judges Carrie Ann Inaba, Len Goodman and Bruno Tonioli, who awarded her with the highest score of the night: 29 out of 30.
This was the third consecutive week that Lake and Hough outperformed their competitors, and they became the first couple during Season 13 to earn two 10s from the judges.
"This was a blockbuster performance worthy of three sequels," Tonioli, 55, raved. "The thrill of the chase, the buildup of tension, the chilling ending. It really was an immaculate tribute to the master of suspense [Alfred Hitchcock]."
