13. He plays a key (handsy!) role in a hip-hop video
Affleck cradling J.Lo's butt in her 2002 "Jenny From the Block" video was the peak of the celebrity union known as Bennifer -- and a career low for Affleck. (He has since called the year he dated J.Lo his "annus horribilis.")
14. He revealed his affair with J.Lo in a newspaper ad
"You have shown kindness, dedication, diligence, humility, graciousness of spirit, beauty in courage, great empathy, astonishing talent, real poise and true grace," Affleck wrote in an several-thousand-dollar full-page Hollywood Reporter ad in 2002, congratulating a then-married J.Lo on being named ShoWest's Female Star of the Year (also known as the most expensive pickup line ever). His gushy sign-off: "I only wish I were lucky enough to be in all your movies ... With love, respect and gratitude, Ben Affleck.''
15. And then she wrote a song about him
"I think God made you for me, a mix of passionate fidelities," J.Lo sings in her 2002 track "Dear Ben." "I write this song to let you know that you will always be my lust, my love, my man, my child, my friend, and my king." Didn't exactly work out that way, but we respect the sentiment.
16. He has some seriously terrible tattoos
After his breakup with Jennifer Garner, Affleck shocked his exes by splurging on the quintessential midlife-crisis tattoo: a massive back piece of a phoenix rising from the flames. But this isn't Affleck's only ink mishap. Among many others, he has: a dolphin on his right hip, which he got trying to cover up an old tattoo of a high school girlfriend's name, and an unsightly splotch on his right shoulder from another bad decision. "I was 16," he says, blushing. "I got a fake ID, went out and got a tattoo of barbed wire. Then I decided I didn't like the tattoo," Affleck told the New York Times, explaining that he got roses etched over it. "I didn't like the roses, either."
