“Paris Hilton, and the entire family was there,” the source said. “Everyone but Kyle. And none of Kyle’s kids were there either.”

“Kyle also didn’t attend the funeral over the weekend,” the source said. “No one mentioned Kyle’s absence.”

Because Umansky left Hilton's real estate firm, Hilton & Hyland, years ago to start a firm of his own, The Agency, the familys have been at odds.

As for how Kim Richards is coping with Brinson's passing, the source added, “Kim seemed to be at peace with the situation. Of course she misses Monty, but she is coping with the loss in a very healthy way.“
