Looks like there's tension between Kate Gosselin and Tony Dovolani.
In a rehearsal clip shown during Monday night's Dancing With the Stars, Gosselin whined that she's "stressed" while Dovolani complained, "Nothing in dancing is natural to Kate."

"He feels like I undermine him as a teacher," Gosselin, 34, snapped to the camera before turning to Dovolani. "You're not taking into consideration how I learn!"
Gosselin walked away saying, "I'm done, I'm done today."
Dovolani then removed his mic pack and said, "I quit!" The reality mom broke down in tears and exclaimed, "I don't get it!"
Shortly after, Dovolani admitted he "overreacted," and Gosselin -- who split from her husband of 10 years, Jon, last year -- lamented, "A lot of people quit on me in my life."
Their dance was just as disastrous as rehearsal. Gosselin shook her head as she missed steps, mouthed the counts and rolled her eyes. Afterwards, judge Bruno Tonioli called their routine a "nightmare... you go through the motions like a Stepford Wife. You need to get acting lessons!"
Gosselin's response? Another eye roll.
Carrie Ann Inaba said she sensed Gosselin's “fear,” and Len Goodman noted, "Your nervous are breaking you. Don't go down as a wimp, go down fighting!"
They earned a score of 15. Combined with last week's scores, they have 31 out of 60.

After the credits rolled, she hugged Dovolani and said, "I'm so sorry." He patted her on the back and they spoke calmly about the routine.
Gosselin and Dovolani have been flying back and forth between Los Angeles, where the show tapes, and Reading, Penn., where Gosselin has built a rehearsal space in the basement of the $1.2 million home in which she lives with her eight children.
Despite receiving the third lowest scores last week, Dovolani told UsMagazine.com earlier this month that Gosselin is "driven" to win.
Last Monday, an audience member said she "looked so nervous the entire time."
