One of the most important and challenging things for any recovering addict is staying clean once they get out of rehab. 'Celebrity Rehab' chronicled their time within the treatment facility, but with 'Celebrity Rehab Revisited' (Sun., 9PM ET on VH1), we got to see the staff checking in with former patients out in the real world to see how they're faring.

Head Counselor Bob Forrest got Jaimee Foxworth to agree to a drug test, but didn't tell her it would go back 90 days. It was an extra check to make sure she'd been able to stay clean, and the results came back fantastic. No marijuana, sleeping pills or any other drugs that they could detect.

Foxworth was simply beaming, and said she was proud of herself for her accomplishment. Valuing this achievement as she clearly did is going to help her maintain her sobriety in the future as well.
