David Hasselhoff has fallen off the wagon again, the NATIONAL ENQUIRER reports

The 55-year-old actor suffered a severe drinking relapse and was readmitted to a Los Angeles hospital to detox on Oct. 8, the NATIONAL ENQUIRER reports in its new issue.

"David does so well staying sober and then something kicks in and he's back drinking," a close source told the NATIONAL ENQUIRER.

Weak and trembling, David was readmitted to Cedar Sinai Medical Center, where doctors began the detox process.

"He looked awful when they brought him in," said the source. "His color was ashen. He felt sick. It was just so sad."

"David was so humiliated," said the source.
