John Stamos Finishes Rehab, Tweets He's 'Healthy' And 'Grateful'

John Stamos is out of rehab.

On Friday, the "Grandfathered" actor tweeted, "I'm back!" and announced he has finished his month-long stay in rehab. The actor said he is feeling "healthy" and "grateful" for the support of his friends and family.

Earlier this month, Stamos checked into rehab for substance abuse  following his DUI arrest in Los Angeles. In June, the "Full House" actor was arrested and briefly hospitalized  for driving under the influence. His time in rehab prevented him from co-hosting the 2015 Emmy Award  nominations announcement, but Stamos is still expected to reprise his role as Uncle Jesse in Netflix 's upcoming "Fuller House ."
