'DWTS': Rob Scores High and Talks Kardashian Birthdays and 'SNL'

On Monday night's "Dancing with the Stars," host Tom Bergeron noted to a high-scoring Rob Kardashian, "You had the best week of any Kardashian!"

Rob, who danced the quickstep with partner Cheryl Burke, said, "It was Mom's birthday on Saturday. It was Lamar's birthday yesterday -- my brother-in-law. My little sister, a couple days before that." When asked how he plans to celebrate, he answered, "We are all going salsa dancing!"

Rob also opened up about the "SNL" spoof on his family that aired last Saturday, saying his family is cool with being lampooned. "If they're doing a parody of you, it's usually a good thing."

Rising to the top of the leader board with the season's first perfect score were J.R. Martinez and Karina Smirnoff, who performed the Waltz. Following the dance, Martinez said, "I want to thank my mom, God, Justin Bieber. I'll never say never!"

Maks Chmerkovskiy and Derek Hough, both the subjects of a nasty tabloid story claiming they are bitter enemies locked in a dance war, held up the magazine and took a photo before posting it on Twitter. Derek explained, "I was him reading it on the couch... and he said, 'Derek, hey, look at this.'" Maks added, "So Derek and I took a picture with the spread."
