The DWTS competitors hit the rehearsal studio this week, and they opened up about their competitive drive, and how it's going to give them an edge against the show's other couples, in ET's exclusive preview clip.
"Brandon is young, he's fun, he's cool, we have a good vibe," the 25-year-old "No Drama" singer explained. "We're both really competitive. I know he wants that Mirrorball [trophy], I certainly want that Mirrorball."
"So I can't wait to get on the dance floor and show America what we got!" she added.
Armstrong couldn't agree more, saying, "I think the chemistry's great!"
"I got the phone number, so I think the chemistry's going smooth," he joked with a laugh.
This marks Armstrong's first time as a pro, after working as part of the DWTS troupe for the last three seasons, having signed on during season 24.
Tinashe arguably has the most dancing experience among her fellow slate of stars going into this season, but if DWTS has taught fans anything during its years on the air, it's that anything can happen -- and winning is as much about personality and chemistry as it is about footwork and flawless execution.
