Most stars dread aging - Reese Witherspoon isn't among them.

"I think as a woman, you get older, you feel more confident in your sexuality," she tells the January issue of Glamour, according to JustJared. "You’re not as intimidated by it, not as embarrassed by it. Sexuality and femininity is an accumulation of age and wisdom and comfort in your own skin. I feel better - so much better now than I ever did in my twenties." (She was 30 when she announced her split from actor Ryan Phillippe.)

Says the actress, "I am calmer; I know who I am. And as a result, I feel much sexier.”

Her message to actresses who feel all the good roles go to younger women? “There’s always going to be somebody younger or sexier," she says. "That’s why I like to say, and it’s become my famous line, ‘Funny doesn’t sag.’”

When it comes to romantic comedies, she says, "I watch them all the time. I love all my fellow female romantic comedy queens, like Jennifer Aniston, Jennifer Garner and Katie Heigl. I also think that the questions romantic comedies ask about men and women are universal.”

As for her own love life, Witherspoon is happier than ever these days. Sources recently told Us Weekly that her beau, agent Jim Toth, has been eyeing engagement rings.

Witherspoon - mother to Ava, 11, and Deacon, 7 - tells Glamour expanding her family is inevitable.

"I would love to have more kids," she says. "Kids are the best part of my day. I don’t wake up to make movies. I wake up to hang out with my family.”
