Many people believe that having sex before getting married is simply wrong, and Adriana Lima is one of those. If most people find it hard to remain a virgin until their wedding day, you can only imagine what the now ex-husband of the incredibly gorgeous Brazilian top model (one of the most famous Victoria's Secret Angels) must have gone through before the couple finally tied the knot in 2009, when Adriana was 28. Funny thing is, just four months after the couple got married they announced that Adriana was three months pregnant. Jessica Simpson Many people might not know this, but singer and actress Jessica Simpson has always been an extremely traditional and religious woman despite her sexy outfits and attitude. That is why she promised her father and her then boyfriend Nick Lachey that she wouldn't lose her virginity until she was married. And, apparently, that is exactly how it went. Jessica and Nick got married in 2002 and ended up filing for divorce just three years later. Kevin Jonas The three Jonas Brothers used to wear promise rings when they first found fame and Kevin is the only one who is married. Apparently, he kept his promise, what isn't sure is whether his brothers did too. Carrie Underwood The gorgeous country singer is another who vowed to stay a virgin until marriage and, apparently, she kept her word and didn't have sex until she married Mike Fisher in 2010. Gary Coleman The now deceased actor didn't have sex until he married Shannon Price in 2007, just three years before his tragic death.
