Everyone needs some R&R once and a while.

Khloe Kardashian and Tristan Thompson are currently on vacation with Kendall Jenner and her beau Ben Simmons in Mexico, and it looks like the whole group is enjoying their time south of the border.

Pix surfaced of the group relaxing by the pool, and partying it up in a Puerto Vallarta nightclub with family pal Joe Francis.

The Revenge Body star and her baby daddy couldn't keep their hands off each other and were kissing and cuddling, so she must not believe - or care! - about those reports that the NBA star was reportedly cheating on her again during a recent visit to Toronto.

"There was a woman in Tristan’s entourage and it wasn’t Khloe. They looked like more than friends because he had his hand on her lower back when they arrived. There was definitely something there," a source dished to Radar.

"She was a beautiful, young girl who looked as if she could be a model. She, along with one of his security detail, stayed in the locker room while he taught camp. He appeared to be in a hurry to get back to his female companion because he jetted out of the center the minute it was over," the source added.

Unfortunately, it sounds like it's going to take a very embarrassing public scandal to get the reality star to dump her unfaithful beau once and for all.

"She simply can’t cut the chord and always seems to find a way to talk herself out of leaving him, even though her head tells her all day every day that it’s not right. She even tried to pack her bags on numerous occasions and make arrangements to move in with her family, but when push comes to shove, she never goes through with it," an insider revealed.

Kenny might be the only one of the K clan that can tolerate spending time with Tristan these days!
