Scott attended the DAER Nightclub Hotel & Casino Atlantic City Grand Opening Weekend on Saturday night.
Other celebs who made it out included DJ Tiesto and rapper Ludacris, both of whom performed throughout the evening.
Scott dressed rather casual for the occasion, pairing a black t-shirt with some dressier pants and black shoes.
Kourtney, on the other hand, has been living her best life overseas in Italy with her boyfriend Younes.
This included romantic evenings out, boat rides with her children and even an intense game of Connect Four.
Do you think Scott is jealous of Kourtney and Younes' relationship? Sound off in the comments!
