Kendall Vertes walked out from their rehearsals as the promo clip for Episode 13 of "Dance Moms" Season 6 released. Some are worried that the kids are getting too involved in the drama.

The short video is now available on YouTube, and it was quite shocking to see that the young aspiring dancers are starting to get affected to the conflict. Read the brief summary below:

The episode is entitled "ALDC Does Vegas" that reads as "The ALDC heads to Las Vegas; Ashlee and Brynn are now official members of the team; Kendall stands up to Ashlee for the first time; the mothers are concerned that the girls are becoming too involved in the drama."

As transcribed, IB Times noted that Jill yells "I am not allowing this woman to talk to my child like that!"  as Kendall can be seen approaching Ashlee. Viewers have watched in the previous episode that Ashlee accused the ALDC moms of being "mean" to her daughter. And for that, Kendall had decided to "stand up to Ashlee for the first time."

While there is a drama stirring among the dancers and their moms, they are still heading to Las Vegas for the weekly competition. The elite junior team will perform a tribute to the late David Bowie "You have to go out there and portray what David Bowie stood for," as head Abby Lee Miller tells her students in the promo.

"Dance Moms" Season 6 Episode 13 will air on Tuesday, March 29, at 9 p.m. EDT on Lifetime.
