"[Our chemistry] wouldn't be as good if something [romantic] were to happen between us," MacManus told reporters backstage after Monday night's premiere of Dancing with the Stars: All-Stars, according toPeople.
"Everything we're kind of building towards is about that frustration. And that's where the chemistry is. The chemistry is about that tension."
Chemistry with her partner is apparently one thing Anderson -- who had originally finished in sixth place on Dancing with the Stars' tenth season in 2010 -- has going for her in the competition, but the actress insisted she has more to show viewers.
"I know I bring other things to the table. I know I'm not the best dancer, but I have a lot of heart and I have a lot of guts, and I want to be able to portray that," Anderson explained, adding she wants to remain in the competition very badly.
"This gives me an opportunity to be myself and be good at something. It's emotional, too. It's this whole weird thing. I've got to stay in it. I promise I won't let you down."
As for MacManus, he told reporters he's not ready to pack up just yet although he and Anderson had earned the lowest score of the night with 17 out of 30 possible points for their cha cha routine.
"I'm going to go home and work on next week," said the pro dancer, according to People. "No matter what happens, we can't do anything about tomorrow, so I have to turn my attention to next week."
