"I'm gonna be so mad if I've blown it," Stirling says through tears in footage obtained by TMZ. "We've worked so hard."

When she asks her partner Mark Ballas what happens if she can't perform on Monday night's episode of "Dancing With the Stars," Stirling is told that she'll have to forfeit. 

As per the show's rules, celebrities must compete each week to remain in the competition -- though, if their pro partners aren't able to dance in a given week, they're replaced by temporary substitute pros.

Stirling has been a front-runner during the show's current 25th season. Last week, Stirling and Ballas received a perfect score for their performance.
