John Stamos has been a staple in Hollywood ever since he became everyone's first crush while playing Uncle Jesse [1] on Full House, but while the world has always adored him, he admits that he did go through quite a rough patch in recent years. The ridiculously handsome actor [2] stopped by The Howard Stern Show on Monday and opened up to the host about everything from his divorce from Rebecca Romijn [3] to his mother's death to his stint in rehab in July 2015 [4]. And what's most shocking, John also admitted that he accidentally got a woman pregnant when he was in his late 20s. Read on for his most honest quotes [5], then check out his recent hangout session with the world's other eligible bachelor, Ben Higgins [6].

On entering rehab after being arrested for a DUI: "I had a horrific DUI, which I'm so embarrassed by. I could have hurt somebody. It was really stupid and ignorant of me. I hated myself for that. It was a bad, bad thing."

On why he needed to enter rehab: "I really don't have anything to hide anymore. My father passed away and I got divorced and it sent me down a wrong path . . . [My mom's death] knocked me off . . . I lost myself. I lost my sense of discipline, which my dad taught me so well. More and more I was just dipping into that dark place. It was getting darker and darker. It stunted my growth emotionally. Maybe I would be married with kids right now."

On how his mom helped him deal with his divorce: "We needed each other and she needed me and [after his father's death], I sort of became my father and she sort of became my wife — obviously not in a weird way. It was a big part of my purpose for many, many years to be there for her and be a good son."

On getting a woman pregnant in his late 20s: "It was just bad timing. It was sort of a mutual decision," he said of her subsequent abortion. Today, he says children are the "only thing that's missing" from his life.

On his fear of rejection: "I always think that I'm going to be turned down, and that's the scariest thing for me. Yes [I have been turned down], but not a lot."

On making sex tapes: "For the few times I've done it, I have the video and I have it on a hard drive in my safe."
