The Lord can't escape his bad behavior!

Scott Disick arrived to catch a flight out of LAX on Sunday, and the reality star was peppered with questions about his sobriety, alcohol addiction, and alleged cheating on partner Kourtney Kardashian. LD took it all in stride, though, and didn't snap when they followed him when they continued to quiz him.

The father-of-three has endured a well publicized battle with booze for years now, but the infidelity allegations are somewhat recent! "Scott was taking cocaine and doing Xanax while he was in NYC. He was out of control. He had sex with this hot 21 year old he met in the club. They holed up in his hotel room for days," a source dished to Star.

He's skating on thin ice, because the insider claims the brunette beauty is prepared to kick him to the curb and take on being a single mom!

"Kourtney is prepared to raise the kids alone. She basically feels like she has been anyways. Living with Scott is like having a fourth child – she actually thinks that it will be easier without him," the source added.

It's time to stop jet setting and spend some time winning back your family's trust!
