Ballas: 'Melissa Joan Hart talks a lot'

Mark Ballas has joked that his Dancing With The Stars partner Melissa Joan Hart never stops talking.

The dancer, who won last season's competition with gymnast Shawn Johnson, told People that his nickname for Hart is Tangent.

"She can talk... a lot and about the most random things, because one thing will set her off," he explained.

"And she will talk about that forever, and that will link to something else, and that will link to something else... and then 20 minutes will go by."

When asked if she has a nickname for Ballas, Hart replied, "Bossy", prompting Ballas to say: "She thinks that I'm mean. She wouldn't last five minutes with Maks [Chmerkovskiy]."

Dancing With The Stars airs tonight on ABC.
