Twenty-two was the lucky number for Jessica Simpson, too. The singer/actress/former-realty TV star waited until she married Nick Lachey in October 2002 to consecrate their relationship in the biblical sense.

I know that condoms are not a hundred percent, because I'm here because of a busted condom," she said.
