Most of the Kardashian family came out to watch Rob perform his cha-cha with partner Cheryl Burke on Dancing With the Stars in LA last night. Kim was joined by her husband, Kris Humphries, while Khloé had her one-and-only, Lamar Odom on her arm. Kris and Bruce Jenner were in the audience cheering on Rob, as Kim was busy cooking up a voting scheme for her younger brother. Kim Kardashian tweeted to fans, "OMG I have @JustinBieber 's phone #!!!! 800 8683402! CALL HIM! He's taking calls for the next hour!!!!" and later followed up with, "Ok guys obviously I'm joking, that's not Justin's #! But seriously call & vote for @RobKardashian & @CherylBurke 800 8683402!!! Xoxo." Kim famously competed on the show in 2008 so she knows the importance of votes; however, Rob may be out of harm's way after scoring a solid 22 for his latest routine. Fellow contestant Hope Solo might be on the chopping block tonight following a heated exchange between her dance partner, Maksim Chmerkovskiy, and head judge Len Goodman. Len commented that Maksim and Hope put out the "worst dance of the season" to which Maksim replied with "maybe it's time to go! [retire]" in regards to Goodman's 50 plus years in entertainment.
