Romeo may be portrayed as a flirt on Dancing with the Stars, but Chelsie Hightower says the rapper is all business this week after getting tepid critiques for their rumba. "We are working our butts off!" she tells TVGuide.com. "We joke around, but our main goal is to focus on the dancing and we're working extra-hard this week to come back stronger with our paso doble." Making their comeback slightly more difficult is the show's first classical week, which will feature a 46-piece orchestra for each couple's dance — not exactly the type of music that goes with the paso.
