John Stamos, who got a DUI last year and spent a month in rehab for substance abuse, got really candid on "The Howard Stern Show" Monday. 

Stamos laid it all out there, talking about kicking his Ambien habit, divorcing Rebecca Romijn and deciding to terminate a pregnancy with a woman he impregnated in his 20s. His DUI, he said, was a big setback and a wakeup call.

"I could've hurt somebody, " Stamos, who said his divorce "sent me down a wrong path," told Howard Stern. "It was really stupid and ignorant of me. I hated myself for that."

The 52-year-old, who said the aforementioned surprise pregnancy in his 20s was "bad timing," also let us know how to find the sex tapes he's made, in case that bottomless spread in Paper magazine wasn't enough. 

"I have the video, and I have it on a hard drive in my safe," he said.
