After hitting up the MTV studios and making a pit stop at Pinkberry, Kim and Kris headed backstage at Dancing With the Stars to pump Rob up before his big show, on Monday.
The Kardashian clan gathered to rally around their little bro Rob, who has managed to remain on the show despite earning some of the lowest scores this season.
Rob opened DWTS with his cha cha cha, and big sis Kim won him a ton of votes with her sneaky Tweet: "OMG I have @JustinBieber 's phone #!!!! 800 8683402! CALL HIM! He's taking calls for the next hour!!!!".
Many "Biebettes" had their hearts broken tonight, courtesy of Kim!
Kardashian quickly corrected her Tweet, confessing: "Ok guys obviously I'm joking, that's not Justin's #!"
