Lisa Vanderpump is seen chatting with James Kennedy during a new sneak peek at Monday's episode of Vanderpump Rules, and during their conversation, Vanderpump gives Kennedy a piece of her mind.

As Kennedy fumes about the then-recent arrest of Jax Taylor, claiming it is "embarassing" that Taylor is still employed by Vanderpump at SUR Lounge, Vanderpump reveals he's been suspended, but still, Kennedy's rant rages on.

"I actually don't need any help from pipsqueak busboy running my business," Vanderpump said of James. "So, thank you, James Kennedy, but I will pass on your managerial advice."

Kennedy continues on, telling Vanderpump and her son, Max, that he hopes Taylor will be taken to trial for her shoplifting arrest, and saying that he needs to be taught a lesson. But Vanderpump doesn't think it's Kennedy's place to speak of Taylor.

"You're acting like a little brat," Vanderpump cuts in. "You need to grow up."

"I don't know who James thinks he is, but the way he's raising his voice is kind of getting out his pram. He needs to get right back in it," Vanderpump continues in her confessional.

Taylor was arrested after stealing a pair of sunglasses in Hawaii, and in turn, his co-stars were forced to bail him out a couple of weeks ago on the show.
