The couple did a sensual rumba to Foreigner's "Waiting For a Girl Like You" during the Instant-Dance challenge, which gave the couples roughly 30 minutes to finalize the choreography to a song randomly picked at the beginning of the show, Grey's routine was filled with quick and slow movements that were well appreciated by all the judges. Judge Bruno Tonioli called it "flawless," and Len Goodman said, "that's what makes great dancing, and that's what we've just seen."

Their quickstep earlier in the night earned straight nines, which gave them a  total of  57 out of 60 points.

Brandy and partner Maksim Chmerkovskiy tied Grey for top spot and first earned 29 points with their Waltz.  Tonioli called it "poetry," while judge Carrie Ann Inaba said she was was "riveted" by her performance. Their cha cha in the instant-dance challenge earned the two 28 points.

Meanwhile, Kyle Massey and Lacey Schwimmer came in at second and earned 56 points with their Viennese waltz and energetic instant jive to "Good Golly Miss Molly."

"You've become this kind of sophisticated, refined young man. You're a nice young man!" Tonioli raved.

At the bottom of the leaderboard, once again, was teen mom Bristol Palin with a total of 47 points. Although her first dance, an Argentine tango, with partner Mark Ballas showed grace and confidence, judge Goodman said  it lacked "intensity." Palin later showed off her shimmying skills while dancing the Samba, which earned 23 points.

And just a point ahead of Palin was former NFL star Kurt Warner, who earned a total of 48 points with partner Anna Trebunskaya. The couple first danced the waltz to The Eagles "Take It To The Limit," which was well received by the audience. The judges commented on a few technical flaws, while Inaba said, "You are sort of not quite at the same level as some of the other people." Their instant cha cha was also a crowd pleaser and earned three eights from the judges.
