In the August 2011 issue of Cosmopolitan magazine, Justin Timberlake talks openly about some of his favorite things women say or do that turns him on.

From the way she dresses to the way she can talk "nasty" ... Timberlake throws it all out on the table as he shares the different sexy traits his ideal woman must have if she's going to roll with the 30-year-old. Here is what the singer/actor (who stars in the upcoming movie 'Friends With Benefits') had to say!

On not caring what others think: "I like a woman who doesn't necessarily care if other people like her. She is who she is and figures people can take it or leave it."

On the way she talks: "There's nothing better than a pretty girl with a nasty mouth. It's every guy's fantasy."

On the way she dresses: "It's not appealing when a woman dresses to please a man. It's way more attractive if she has her own distinct style and wears what she feels best in."

On being up for anything: "There's something magnetic about someone who is always up for new experiences and doesn't shut anything down without considering it."

On being spontaneous: "It's nice when you meet a woman who can enjoy the experience of whatever we're doing together instead of planning what we're going to do next."

On being honest about her feelings: "I have a mother -- I don't need a girl to tell me what to do. What I do like is a woman who has the guts to tell me exactly how she feels."

On being able to hang with the boys: "If she can hang with the guys without trying to be one, it is very sexy."

On calling him out when necessary: "I fully believe females are smarter and more evolved. And I'm sure it's easy to get frustrated with guys, so it's really nice when a woman will calmly explain something he may be doing wrong in their relationship."
