Kourtney Kardashian reportedly accompanied her baby daddy Scott Disick to Las Vegas, and she invited sisters Kim Kardashian West and Khloe Kardashian to go along, too. Scott Disick was scheduled to appear at 1OAK Nightclub at The Mirage Hotel & Casino in Las Vegas on Sunday night, and Kourtney didn’t want him getting drunk or cheating on her.

“It is believed that they are going to shoot an episode of the show (Keeping Up With the Kardashians) there and all of the girls went with him because they need to help him do a PR cleanup of the mess he made on his last round of club appearances,” a source told Yahoo NZ.

“Kourtney, Kim and Khloé are not going to allow him to get drunk while they are around and they are saying this trip is a good opportunity for them to come together and iron out their differences,” the source shared prior to Saturday night’s event.

Kourtney Kardashian and Scott Disick have long had issues in their relationship, based mostly on his inability to stay sober and to put his family ahead of his partying lifestyle. Scott and Kourtney have three children now. Mason Disick is five, Penelope is two, and new baby–son Reign–is only two months old.

So why did Kourtney Kardashian want Kim Kardashian West and Khloe Kardashian along on this little adventure?

“Kourtney doesn’t always get real with Scott, but Kim and Khloé never hold back and are not afraid to tell him what they think. They have no problem putting him in check. Scott always surrenders when the three of them are guarding him,” the source explained.

RadarOnline reports that Kourtney Kardashian did in fact accompany Scott Disick to Vegas on Saturday night.

She’s very fortunate sisters Khloe and Kim were able to make it. The two–along with sister Kendall Jenner and Kim’s daughter with Kanye West, North West, were in a car crash in Montana earlier that same day.
