Katie Slams Two-Timing Jax In Awkward Preview Video

Will Jax Taylor ever be a one-woman man?

In a preview for the upcoming episode of Vanderpump Rules, Taylor's costar Katie Maloney calls out the 36-year-old bartender for playing the field.

The tense confrontation is sparked when Taylor's new girlfriend, Brittany Cartwright, goes into Sur for a job interview with Lisa Vanderpump.

While Cartwright talks with the RHOBH star and entrepreneur, Maloney lectures Taylor about being committed to his new relationship in the next room.

"I don't want you to make a bunch of promises to her," Maloney berates Taylor. "You brought Carter just a few days ago to Scheana's birthday and now Brittany's here. Do you see the way you kind of bop around?"

In the middle of Maloney's disatribe, new coworker and cast mate Lala Kent shows up and Taylor invites her to go out with him the next night.

This sets Maloney off.

"Jax takes the whole out of sight, out of mind thing just a little too far," she complains. "Brittany is just in the next room! Even if she is not there, she's still there."

She takes one more swing at him after Kent reveals that she lives in the same apartment that Taylor's ex Stassi Schroeder used to rent.

"I always thought that Jax would do just about anything to get back in Stassi's bedroom, and now he can just do Lala," Maloney jokes.

As Kent finally walks away, Maloney warns Taylor to not "break any more hearts" and says the he should learn how to "control" himself around other women.
