Rachel Bilson has revealed the secret behind her sex appeal is confidence. The brunette actress is best known for playing Summer Roberts in hit teen show ‘The O.C.’ believes all men find confident women attractive because they are sure of themselves. She said:

“The best thing a woman can be is confident. Men like that.”

Looks like she was shopping for a dress! I am sure the store loved it, and all the free press that got from it. But she is definitely cute and better then alot of the other young celebs. At least shes taking the break up well from what we can see.

Rachel Bilson and Adam Brody, who play a cute couple on The O.C. and have also dated offscreen since 2004, have decided to call it quits.

“They’ve been done for a few weeks,” a friend close to the couple tells Life & Style. “They are just done. That’s all there is to it. There’s no drama. They just ended it.”

That may explain why Adam showed up solo to a party on Nov. 28 for the U.S. premiere of Volkswagen’s concept car Tiguan in LA.

“He was definitely acting like a single guy,” an eyewitness tells Life & Style.

According to nightlife insiders in LA, he’s been spending a lot of time without Rachel at the clubs with his guy friends.

Reps for the two would not comment.
