Women dig bad boys -- it may be the oldest cliché but turns out, there's a scientific reason behind our penchant for sexy and rebellious cads. No, it's not because we're addicted to trouble. Blame it on hormones for clouding our judgment.

When ovulating, a woman's hormones influence who she sees as good potential fathers, and they pick sexier men over obviously more dependable guys, says a new University of Texas study.

The researchers had women look at dating profiles of either a sexy man or a reliable man. Somehow, women who were near ovulation thought that the sexy man would contribute more to parenting and domestic duties. (i.e. caring for the baby, shopping for food, cooking and contributing to household chores.)

"Under the hormonal influence of ovulation, women delude themselves into thinking that the sexy bad boys will become devoted partners and better dads," says study researcher Kristina Durante. "When looking at the sexy cad through ovulation goggles, Mr. Wrong looked exactly like Mr. Right."

But interestingly, these ovulation goggles appear to trick women only when it comes to choosing their own partner. "When asked about what kind of father the sexy bad boy would make if he were to have children with another woman, women were quick to point out the bad boy's shortcomings," says Durante. "But when it came to their own child, ovulating women believed that the charismatic and adventurous cad would be a great father to their kids."
