They're doing what they do best... spending her dad Lionel's cash!

Scott Disick and girlfriend Sofia Richie are currently on vacation in Mykonos, Greece, and we're not sure why they jetted off for some rest and relaxation, because it's not like they're working hard when they're at home in LA! Perhaps they're just trying to one up Kourtney and her Italian summer?

The controversial pair's romance is back on solid ground after a brief split, which was brought on when LD allegedly cheated on the 19-year-old model during a working trip to Miami. She has clearly forgiven and forgotten, because she recently moved back in with the bad boy reality star in his Calabasas mansion.

If you believe the rumors, The Lord always held out hope that he would reconcile with his baby mama, but he's starting to lose faith now that she's so serious with boy toy Younes Bendjima.

"Scott assumed they’d go off and do their own thing for awhile and inevitably get back together. A few years have passed now and Kourtney has shown no sign of being remotely interested in Scott anymore, beyond being the father of her kids,” a source dished to Radar.

Is he going to follow Bieber's lead and pop the question? All the cool kids are doing it!
