We can always count on celebrities to say things in public that many people would only be comfortable revealing to a best friend (if that). Whether it's intimate details about their sex lives or personal grooming habits, we're guessing the stars below are just so accustomed to having cameras and mics in their faces that they simply forget -- or just don't care -- they're always on the record.

Angelina Jolie: A Bloody Mess

"I had started having sex with my boyfriend at 14 and the sex and the emotions didn't feel enough," Jolie told OK! magazine in 2007. "In a moment of wanting to feel closer to my boyfriend, I grabbed a knife and cut him. He cut me back. We had an exchange of something and we were covered in blood, my heart was racing."

Enrique Iglesias: The Best Things Come in Small Packages

Midway through a 2011 concert in Australia, Enrique probably disappointed a lot of hopeful groupies when he told the crowd, "What does Spanish good looks have to do with the size of your penis? Maybe I have the Spanish looks but I have the smallest penis in the world. I'm serious."

Jada Pinkett-Smith: Limo Lovin'

Jada, married to Will Smith since 1997, likes to talk about their sex life -- a lot. Among her many notable quotes, she told Shape magazine in 2009, “When you have three kids, you've got to take your opportunities when they come. In a limo, on the way to the Academy Awards this year, Will started looking at me in this way that drives me wild. We started kissing passionately, and the next thing I knew, well, let’s just say we missed the red carpet and I ended up with almost no makeup on.”

Robert Downey, Jr.: Hands On Man

Before he married his wife, RDJ found ways to keep his hands occupied. “I was a compulsive, serial masturbator," he told the U.K.'s Sunday Times in 2008. "But it was the best thing I could have been. I utilized that organ and rode it for everything it was worth.”

Tori Spelling: Help Trimming the Hedge

In her autobiography 'Mommywood,' the actress and reality star said that during her (many) pregnancies, she's needed her husband's help to keep the lady-lawn mowed. "I'd say, 'Dean, how's it looking down there? Do I need to shave?'" she wrote. "But of course I couldn't shave. So Dean had to shave me. He'd hold up a mirror and say, 'How'd I do?' Or he'd take a picture with his BlackBerry to show me."

Tyra Banks: Self-Cleaning, But Not Self-Censoring

The former supermodel dedicated an entire 2007 episode of her daytime talk show to female genitalia -- and it was during that hour that Tyra (over)shared, "You know what my mom used to say? That you don’t need douche because the vagina is a self cleaning oven."

John Mayer: Explosive Diarrhea of the Mouth

In an infamous 2010 interview with Playboy, John dropped what is quite possibly the most descriptive overshare of all time. Recalling sex with ex-girlfriend Jessica Simpson, he said, "It was like napalm, sexual napalm. Did you ever say, 'I want to quit my life and just f--ing snort you? If you charged me $10,000 to f--- you, I would start selling all my s--- just to keep f---ing you?'"
