If we didn't know better, we'd think they were one big happy family!

Scott Disick spent Father's Day with girlfriend Sofia Richie and his three kids at the beach in Malibu, and it seems everything is back to normal between the couple after their brief breakup-makeup!

Although, a new report claims the hard partying reality star is just buying his time with Lionel Richie's daughter, and is actually still in love with baby mama Kourtney Kardashian.

"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.

"Scott thinks Kourt is his soul mate, and he’s filling that void with a string of meaningless hook-ups. Even his relationship with Sofia is just to pass the time," the source added.

We've always thought the eldest K sister and The Lord would end up reconciling! Sofia might want to have a chat with her man!
