Robin Williams is once again at a rehab facility, but a source closely connected to the actor said the visit is not because he is struggling with his sobriety.

“This is not about him falling off the wagon,” a source told FOX411. “It’s like an educational and spiritual facility... It’s all very healthy.”

According to TMZ, Williams is at the Hazelden Addiction Treatment Center in Minnesota. Williams has spoken before about his past struggle with cocaine and alcohol addiction. He most recently went to rehab for alcoholism in 2006.

The media got word of Williams’ Minnesota stay when he posed for a picture with a fan at a Dairy Queen near the treatment facility on Sunday.

His rep told us, "After working back-to-back projects, Robin is simply taking the opportunity to fine-tune and focus on his continued commitment, of which he remains extremely proud."
