Campbell blames drug-drink mix

Glen Campbell blamed his drunken-driving arrest this week on the accidental mixing of alcohol and a prescription anti-anxiety drug.

“I’m taking Lexapro and you can’t have alcohol with it, and I did. I forgot. That’s just it in a nutshell really,” the country music star told the East Valley Tribune on Tuesday, the day after his arrest in Phoenix.

Campbell, 67, said he’s been taking the medication to treat anxiety for the past seven or eight months.

The singer, whose hits include “Rhinestone Cowboy,” was arrested Monday after a collision at a Phoenix intersection in which nobody was injured.
