The drama is getting physical on “Keeping Up with the Kardashians.”
Kim Kardashian and Kourtney Kardashian have taken their sibling rivalry to a whole new level.
In a promo for the reality show’s upcoming season, Kim appears to lunge and throw a punch at her older sister after getting into a heated argument.
While it’s unclear what sets off the chain of events, Kourtney throws something at Kim after yelling, "You've nothing to say!”
Kim somehow winds up on the ground. Once back on her feet she responds, “Don’t ever come at me like that,” and takes a swing at Kourtney.
The camera fades to black and Kendall Jenner is then heard saying, “Buttons have been pushed!”
The altercation comes just days after the Kardashian sisters showed a united front as they paid homage to their late father Robert Kardashian over the weekend.
In a series of tributes, the sisters honored the family patriarch on what would have been his 76th birthday.
Kim, Kourtney, Khloe and Rob Kardashian all shared sweet throwback photos alongside their dad to honor his memory.
Based on the new teaser, Kim and Kourtney’s beef is the centerpiece of the new season, which sees the long-running series move from Sundays to Thursday nights.
Last year, Kourtney also announced that she would be stepping back from the series to spend more time being a mother to her three kids.
Fans will have to wait to see how the turmoil plays out when season 18 of “Keeping Up with the Kardashians” premieres on Thursday, March 26 at 9pm on E!
