Not cool. Little Women: LA star Mika Winkler decided to pull a prank on her co-star Tonya Banks — and Tonya didn't think it was funny at all. In fact, the reality star confronted Mika about it and it got seriously heated. Check out the video above to watch the exclusive clip!

In last week's episode, Mika also stirred up some drama with Tonya, and clearly the two haven't been getting along. In the episode, the ladies took a girl's trip to Slovang, CA, and Mika decided it was the perfect time to basically shame Tonya for getting plastic surgery. "Why'd you get lipo, you weren't fat," Mika told Tonya.

In an earlier episode of the hit Lifetime show, Tonya had started to second guess her decision to go under the knife. Throughout the season, the 53-year-old had been looking forward to her surgery, but right before undergoing the procedure, she wasn't so sure. Once she saw herself all marked up, she said, "I hope I didn't go too crazy too fast." Luckily, it looks like her liposuction experience went well!

Catch the next episode of Little Women: LA, airing Wednesdays at 9 p.m. on Lifetime.
