khol005Khloe Kardashian and her husband Lamar Odom have had their first big TV showdown over his oldest friend.

On a recent episode of Khloe and Lamar, Khloe, 26, told her LA Lakers star beau that his best friend Jamie was neglecting his clothing website Rich Soil, as all items appeared to be out of stock.

Lamar was less than impressed with the attempted confrontation because he had earlier told Khloe that he’d tackle the issue himself.

But embattled Khloe stepped things up a gear by changing the locks on their plush Los Angeles loft to stop Jamie, who has a pad in the same building, coming and going as he pleases.

“Changing the locks on Jamie is me putting my foot down,” she said. “We’re about to set some boundaries. This is one step in the right direction. I’m trying to push Jamie in a good place.”

However, the move led to a nasty confrontation during which an angered Jamie told Khloe to “grow up”.

The heated exchange soon sparked a furious row between Khloe and Lamar, 31, as Jamie quickly telephoned Lamar to report that his wife had been yelling and screaming at him.

But by the end of the episode, Khloe and Jamie called a truce, with Jamie assuring her that he and Lamar had the “business side of things covered”.
