After everyone danced once, they all danced together, competing for additional points.
In the end, one team won both rounds of competition.
Brandy and her partner, Maksim Chermokskiy, tangoed to the top with 26 points.
They also won the rock 'n roll dance marathon for 10 more points.
"I'm happy I trust my partner and I only focused on him tonight," Brandy said. "I only tried to make him proud and then he said, 'If you make me proud, then everybody will be proud.' So that's what I was going for tonight."
Third place in the group dance and triple eights for their paso doble landed Audrina Patridge and Tony Dovolani in second place overall.
"I felt like I was really intense and being aggressive and I even elbowed Tony here in the lip on an accident because I had so much energy being projected," Patridge said.
Rick Fox and partner Cheryl Burke also got triple eights, but a lower score in the group dance put them in a tie for third with Kyle Massey and his partner, Lacey Schwimmer.
Both teams did the tango.
"The tango was the most challenging dance we've had so far," Fox said. "I had sleepless nights. I had a nightmare. It was not a fun week."
The other couple felt the same way.
"I yelled more this week than any other week, but it was definitely worth it and he knows that it's not personal," Schwimmer said. "It's just that we can kick butt on Monday nights."
Jennifer Grey and her partner, Derek Hough, got their lowest score of the season -- 20 -- for the paso doble, but a number two finish in the marathon boosted them to fifth place.
"I just know what feels good, and it doesn't feel good to be off balance and it doesn't feel good to miss your steps and it doesn't feel good to be out of control," Grey said.
Bristol Palin got her best score yet with a 23, but her second-to-last finish in the marathon put her in second to last place.
However, judge Len Goodman said she's gone from chimp to almost a champ.
"I'm just thrilled," Palin said. "I'm just filled with excitement when we get good, positive feedback and the crowd was going crazy and I just thought it was such a good performance."
Kurt Warner and partner Anna Trebunskaya ended up in last for both dances.
"It's always disappointing not to get scores that match what you feel the performance was, but it's part of the deal," he said.
One more couple goes home Tuesday after performances from Heart and Kylie Minogue.
