Seth Binzer, better known as Shifty Shellshock of the one-hit wonder group, Crazytown, is most likely back to smoking crack.

You may have seen him on VH1’s reality show, Celebrity Rehab, in which Dr. Drew Pinsky treated Seth and other celebs for substance abuse.

Seth has been shooting a new, related VH1 reality series called, Sober Living.

While filming on Friday night at GOA nightclub, he disappeared into thin air - and hasn’t been seen since. No one knows where he is, and many involved in production think he’s back to the pipe.

They also believe he is using his money earned from the show to buy the drugs.

Oddly enough, Seth reportedly posted a video on his MySpace page Saturday night, (which I couldn’t find), saying he was checking himself into rehab. But he hasn’t done so as of yet.

If Seth doesn’t return to his sober living home sometime today he will be fired from the show. Thus ending any shot he has at cleaning up.

Hopefully, for his darling little boy Halo’s sake, he will come back.

But I doubt it..
