Watch: Family Tension Heats Up On 'KUWTK'

In two new clips for the upcoming episode of "Keeping Up With The Kardashians" the family tension heats up as Kris and Bruce have a fight over Kris's parenting, and Kourtney is concerned about Scott's business trip to Las Vegas.

In the first clip, Bruce agrees with Kourtney that Kris isn't as good of a mother for Kendall and Kylie as she was for the four older children. Kris is shocked at Bruce for siding against her, but then he lays out the evidence.

The second clip shows Kourtney's disapproval of husband Scott heading to Las Vegas for work. Her concerns are heightened even further when she drops him off at the airport and his co-workers are already drinking and partying.

The new episode of "Keeping Up With The Kardashians" airs Sunday August 7, 2011 at 10 PM on E!
