Let the lord always be with you, even on St. Bart's. A new preview from the upcoming episode of Keeping Up With the Kardashians shows Scott Disick "still causing problems" for the Kardashian family on their August trip to St. Bart's following his split from Kourtney Kardashian.

While Disick, 32, is absent from the luxurious island jaunt, he's enjoying a trip of his own in Puerto Vallarta, Mexico, where he parties with his pals and some ladies. Kourtney, 36, who is attempting to move on from her ex after their July breakup, is seen in the preview still checking up on Disick and his whereabouts.

The self-proclaimed "Lord," meanwhile, has been photographed cavorting around with two girls, which Kourtney sees on her phone. As reported by Us Weekly this past August, Disick chartered a private plane to Puerto Vallarta and checked into the St. Regis with a bevy of beautiful women, including Victoria's Secret model Devon Windsor. 

"This is the first trip without Scott," Kim says in her confessional. "And he's still causing a problem. I just hope it doesn't ruin the trip."

While Kourtney deals with her fair share of baby daddy drama, Kris Jenner's two youngest daughters, Kylie and Kendall, get into a few arguments of their own. Kylie invited her boyfriend, Tyga, to join the family vacation, which doesn't sit well with her model sister.

"You could've taken this time to be with your family," Kendall snipes at Kylie. 

The teaser concludes with Kardashian family matriarch Kris shaking her head and saying, "It's going to be a long week."

Watch above and tune in to the episode on Sunday at 9 p.m. ET on E!
