NEW YORK (CBS) The competition was in full force on Monday's "Dancing with the Stars" as the remaining three celebrities continued to battle for the coveted mirror ball trophy.
The season's last performance round had each partner dance two routines. The first round was an old dance the judges wanted to see improvement on, and the second dance of the night was the freestyle.
All three couples performed well during the first round, but the freestyle routine proved to be a little more difficult for frontrunner Evan Lysacek and his partner, Anna Trebunskaya.
The Olympic gold-medalist and Trebunskaya landed at the bottom after their freestyle to "Footloose." Their dance lacked precision and earned them only 24 points, which brought them down to a total of 52. The choreography was deemed "odd" by Carrie Anne Inaba and Bruno Tonioli thought the pair looked "demented."
"It certainly wasn't what I wanted to see," said Len Goodman.
However, ESPN reporter Erin Andrews inched her way to the top with her samba and "lyrical" freestyle to Heart's "Alone." Her sultry samba, which earned her 29 points, was probably the most memorable performance of the night, as it showcased her level of improvement.
"You moved yourself up three notches," said Inaba after the dance.
Andrews earned a cumulative of 55 points out of 60 and was tied for the lead with Pussycat Doll singer Nicole Scherzinger.
Scherzinger and partner Derek Hough ended the night with a technically sound freestyle that was high-energy and creative. Their routine was nearly flawless, which included various dance styles and bold choreography. Goodman thought the performance was "fantastic" and Tonioli said it was "amazing."
The three remaining couples will square off once more and will dance for scores again on Tuesday night's finale. The top two scorers will then face off for one last dance before the new champ is named. Season 10's previously eliminated stars will also return to the dance floor during the show.
