TALK ABOUT BAD TIMING!

Us Weekly Reports:

Before his weekend DUI arrest, Shia LaBeouf opened up about his struggles with alcohol in Details' September issue (out August 12).

The most shocking revelation: LaBeouf, 22, and his father, a former heroin addict, "would drink together and smoke together," the actor told the magazine, "and it's just a bad deal.

"It's not something that is conducive to being a role model — no iconic actors that I know of have problems like that," LaBeouf added. "And I don't know how to do it like a gentleman. I don't know how to have one drink."

He also opened up about a drunken spat he had in a Chicago Walgreens last November. (He was charged with criminal trespassing; it was later dropped.)

"It was two hotheads," LaBeouf said of the incident. "One completely in the wrong, one who wasn't enjoying his job that night, going at it about minuscule bulls--t."
