Colin Farrell has checked himself into rehab at The Meadows in Wickenburg, Arizona, according to multiple reports.

The 41-year-old actor has been open about his substance abuse issues in the past. According to The Daily Mail, who was first to report the news, Farrell actually voluntarily checked into rehab as a preemptive measure.

"He was overwhelmed for the past year and the urges started to come back with being so busy at work and he felt, eventually, out of control and thought maybe he should get ahead of it before he starts using again," the Daily Mail quotes a source. "He decided to pre-emptively check himself in before it went to a bad place. He didn't want to go down that rabbit hole again."

The Meadows is no stranger to welcoming celebrities. Selena Gomez, Tiger Woods and Kate Moss have all spent time at the Arizona facility. 

ET has reached out to Farrell's rep for comment.

This isn't Farrell's first stint in rehab. In December 2005, the Irish actor checked into a rehabilitation treatment center for addictions to recreational drugs and painkillers. In 2014, he talked to The Telegraph about maintaining his sobriety for years.

"I don't take it for granted and I don't undermine how difficult my journey to getting sober was, but now I'm in a really different life and I don't miss it," he said. "I'm very lucky in that respect because I know people who have had a longer period of sobriety than me and they still miss it every day and it's a struggle for them."

"All the madness and all the chaos and all the people around me got so tiring after a while that I had to find another way, and while I don't live a monk-like existence, I have a new appreciation for solitude that would have terrified me years ago," he continued. "And I'm glad the madness is over. It was interesting to experience, but I'm glad it's passed."

Last May, he told Ellen DeGeneres that he was 10 years sober.

ET spoke to Farrell last October, when he and his The Killing of a Sacred Deer co-star, Nicole Kidman, opened up about filming their intimate love scenes.
