Pussycat Dolls member Nicole Scherzinger is becoming a familiar figure atop the Dancing with the Stars leaderboard.

Scherzinger and professional partner Derek Hough topped Dancing with the Stars' judging leaderboard for the second week in a row and fourth time overall during Monday night's sixth tenth-season performance show.

Monday night's performance show featured the competition's seven remaining couples performing individual Argentine tango or samba routines and then competing in a swing dance marathon during which they were all were on the floor at the same time and eliminated by Dancing with the Stars judges Len Goodman, Carrie Ann Inaba and Bruno Tonioli one-by-one.

The first couple eliminated from the three-minute marathon received four points, the second couple got five points, and so on until the last remaining couple received 10 points.

Scherzinger and Hough finished in first place on the judges' leaderboard after they received 26 out of 30 possible points -- including a perfect 10 from Tonioli -- for their samba routine and 10 points during the marathon.

They were followed by ESPN reporter Erin Andrews and partner Maksim Chmerkovskiy, who received 25 points for their own samba and nine points during the marathon.

NFL star Chad Ochocinco and partner Cheryl Burke finished in third place on the judges' leaderboard after receiving 24 points for their Argentine tango and seven points during the marathon.

Former Baywatch actress Pamela Anderson and partner Damian Whitewood finished one point behind in fourth place after they performed an Argentine tango that earned 22 points and received eight points during the marathon.

Olympic gold-medal figure skater Evan Lysacek and professional partner Anna Trebunskaya, actress and Clean House host Niecy Nash and partner Louis van Amstel, and former The Bachelor star Jake Pavelka and partner Chelsie Hightower all received 21 points each from the judges during the initial individual performance round. 

However Lysacek and Trebunskaya earned six additional points during the marathon -- which, when combined with the 21 points they received from their samba, left them in fifth place on the judges' leaderboard.

Nash and Louis van Amstel finished sixth after receiving 21 points for their Argentine tango and five points during the marathon, while Pavelka and Hightower finished last after receiving 21 points for their samba and only four points during the marathon.

The judges' scoring and home viewer votes that were cast after Monday night's performances will now be combined and one of the seven celebrity and professional pairings will be eliminated on Dancing with the Stars' fifth tenth-season results show tonight at 8PM ET/PT.
