The chat show host earned a perfect 30 from the ballroom show's judges Len Goodman, Carrie Ann Inaba and Bruno Tonioli for her performance of the Samba with partner Derek Hough, putting her in a good position to go through to the final next week.
Speaking of the routine, Len said it was "fabulous, fabulous, fabulous," while Bruno claimed it was "sizzling hot, bright and brilliant".
For her second dance, a tango, Ricki earned 29 points, with an extra eight marks coming from their Cha Cha Relay performance, giving the couple a total of 67.
Socialite Rob and his partner Cheryl Burke managed to match her score of 67, with much praise heaped on his Argentine tango.
Len said: "You started as a goofy outsider, now you're looking like a leading man."
However, he only managed to score 27 and 28 for his initial dances, but topped the list for the third and final dance, gaining an additional 10 points for his Cha Cha Relay.
J.R. Martinez and partner Karina Smirnoff suffered a setback during rehearsals this week when he twisted his ankle, causing problems with his performance of the Paso Doble.
Commenting on the dance, Len admitted his dancefloor abilities had been compromised.
He added: "I know you suffered an injury, but we can only call it as we see it."
For his three dances, the former soldier earned 56 points
J.R. was not bottom of the leader board, with that unwanted honour going to soccer star Hope Solo, who was suffering from serious shoulder pain related to a previous injury.
She said: "I'm in pain pretty much the entire time I'm on the dancefloor."
In total she earned just 49 points, putting her at risk of not making it through to next week's final.
