It's easy to see why a woman might be attracted to the President of the United States -- the fame, the power, Air Force One. But San Francisco artist Justine Lai has taken it to a whole other level with her "Join or Die" series of paintings, which show her in coitus with the U.S. presidents in order.

Of the project, Lai says, "In Join or Die, I paint myself having sex with the Presidents of the United States in chronological order. I am interested in humanizing and demythologizing the Presidents by addressing their public legacies and private lives."

We don't know about all that fancy art talk, but we do know that the graphic oil paintings featuring Lai fellating Lincoln or getting spanked by Ulysses S. Grant are both hilarious and strangely awesome. Check out the NSFW portraits here.

    Christy Turlington Turlington's flawless skin made her the perfect pitchwoman for Maybelline's "Maybe She's Born With It Maybe It's Maybelline" ad campaign, and helped her become one of highest paid supermodels of all time.

    Turlington is married to director-actor Ed Burns, and in 2006 she signed a multi-year deal to return to Maybelline. She also has no problem posing in the buff, as evidenced by her work for PETA.

    Alt has found success as a nutritional guru -- her two cookbooks promoting the virtues of the "raw diet" became national best sellers. She's also gone toe-to-toe with Trump on "The Apprentice."
