Poor, poor Kourt.
Now, reports are coming out that Disick knows what he's doing, and how to make it better. What remains though, is whether he can actually do that.
The source says of Disick:

Deryck Jason Lavigne Whibley is ready to drop his punk rocker ex-wife for good, by removing her name from his!
The Sum 41 singer secretly took Avril's *Lavigne* when he married her—and nearly 4 years after divorcing in 2009, he's ready to do the paperwork!
Deryck filed in L.A. County Court this week to return to his birth name, Deryck Whibley, making it super official!
