9/10/2010 7:00 AM PDT
Kari Ann Peniche -- the Playboy model from VH1's "Celebrity Rehab" -- just checked into another rehab center to be treated for an addiction to methamphetamines ... only this time, her progress won't be aired on television.

Sources close to Peniche -- who you may also remember from the Eric Dane/Rebecca Gayheart "naked tape" -- tell us she checked into an expensive, high-end rehab clinic late last night .. and plans to stay for 30 days.

We're told Peniche is prepared to foot the massive bill for the high-class rehab joint ... which we're told will easily exceed $30,000.
