John Stamos has reportedly entered a rehab facility for substance abuse, less than a month after being arrested for driving under the influence.

People Magazine first reported Friday night that the actor checked himself into a residential program.

The 51-year-old actor had been slated to co-host the 2015 Emmy Award nominations this Thursday alongside Orange Is the New Black star Uzo Aduba. So You Think You Can Dance host Cat Deeley will join her instead.

Stamos is set to star in Fox's new comedy Grandfathered, which premieres this on Sept. 29, followed by the Full House reboot series Fuller House, due sometime next year.

A rep for Stamos replied to Variance, stating only: "We kindly ask for privacy."
