Rob Kardashian is atop Dancing with the Stars' judging leaderboard for the first time ever heading into the second night of the two-night finale of the ballroom dancing competition's thirteenth season.

The Keeping Up with the Kardashians sibling and professional partner Cheryl Burke finished in first place on the judges' leaderboard during Monday night's Dancing with the Stars broadcast, which featured the thirteenth season's three remaining couples performing their first two finale dances.

Each couple was required to perform one routine in a dance style they had not performed yet and a second dance in a freestyle format which allowed them to perform whatever they wished.

Kardashian and Burke -- who had never even finished as high as second on the competition's judging leaderboard until last week's semifinal round -- received 57 out of 60 possible points for their two Monday night routines from Dancing with the Stars judges Len Goodman, Carrie Ann Inaba and Bruno Tonioli.

Kardashian and Burke earned 27 out of 30 points for their initial waltz and then an additional perfect 30 out of 30 points for their freestyle dance.

Former talk show host Ricki Lake and partner Derek Hough finished the two dances tied for second place on the judges' leaderboard with Iraqi war veteran and former All My Children soap star J.R. Martinez and partner Karina Smirnoff with 54 points each.

Lake and Hough received 27 points for their initial cha cha routine and an additional 27 points for their freestyle, while Martinez and Smirnoff received 24 points for their own cha cha and a perfect 30 points for their subsequent freestyle dance.

Dancing with the Stars' live thirteenth-season finale will air tonight at 9PM ET/PT on ABC and begin with each of the three remaining couples performing one additional routine -- their favorite dance of the season.

Afterward, the scores they receive from the judges will be added to their prior finale judges' scores and combined with the home-viewer votes which were cast after Monday night's show to determine which two couples will get to dance in the finale's final "Instant Samba" dance that will determine Dancing with the Stars' thirteenth-season champions.
