COLIN FARRELL has checked himself into rehab . . . but supposedly it's just a PREVENTATIVE measure. He's been sober for 12 years, and his people insist that he's NOT drinking again.
His rep says, quote, "He worked back-to-back projects and just needed a break. He's been sober 12 years, and wanted to do this to make sure he stays that way. He's taking some me-time and doing a tune-up and a reset. This was all his idea."
Colin recently finished production on two new movies . . . the Disney live-action remake of "Dumbo", and "Widows", which also stars Liam Neeson. According to reports, he's at the Meadows clinic in Wickenburg, Arizona.
