Ricki Lake is the one to beat on Dancing With the Stars -- but that doesn't mean she's got it in the bag.

During Monday's episode of the ABC hit, the TV host nearly broke down while rehearsing with pro partner and three-time champ Derek Hough, 26.

"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]."

After hearing the judge's positive feedback, Lake said she regretted wanting to give up so easily. "The highs are so high and the lows are pretty low," she explained. "I'm relieved!"

Carson Kressley was the lowest scorer of the night, earning just 20 points. Chaz Bono, Nancy Grace and Chynna Phillips weren't far behind with 21 points each.
