Turned 40: Oct. 28
The mom of three – her latest, son Henry Daniel Moder, was born in June – and an American Cinematheque honoree, Roberts is one of Hollywood's highest paid actresses. No wonder this Pretty Woman says she has "all I could ever ask for," including a solid marriage. "The widening of my life, and my hips, is really just the true gift of my husband Danny, who I would be so lonely without."

NICOLE KIDMAN

Turned 40: June 20
She's more glamorous than ever, but it wasn't always that way. "I don't know if it happened, or if it was just me making the most of myself," Kidman says of her gorgeous looks. Since she married Keith Urban in 2006, the couple have had ups and downs but, at 40, mom of two Kidman tells Interview, "My husband and I are committed to each other and deeply in love."

KATE WALSH

Turned 40: Oct. 13
Her birthday was the cherry on top of an amazing year for the Private Practice star. In addition to landing her own show, the San Jose-born beauty met movie producer Alex Young and after a whirlwind courtship the two were married in August. "I feel I'm in such a place of peace in my life." Walsh says, "that 40 feels like a great marker of a great year."

LAUREN GRAHAM

Turned 40: March 16
With the end of the Gilmore Girls, Lauren Graham is starting a new era in her life, transitioning to the big screen with the comedies Evan Almighty and Because I Said So. She'll next be seen in Flash of Genius with Dermot Mulroney. But the actress, who also inked a development deal with NBC, isn't all work and no play. "For my [40th] birthday, I rented a frozen margarita machine," she tells InStyle.

"I love being 40," Anderson writes on her Web site. "I've had such a great blessed life and it’s only just begun." The mom of two (Dylan, 10, and Brandon, 11) has started anew in both love and career – spending less time on the beach and more time in Las Vegas assisting magician Hans Klok and, on Oct. 6, tying the knot for a third time, this go-around with longtime friend Rick Salomon.

MO'NIQUE

Turning 40: Dec. 11
Juggling 2-year-old twins and a teenager, Mo'Nique is living a full life – and looking forward to a long one with her former high school classmate and husband Sidney Hicks. The "fabulous and thick" Charm School host, who says she's a size 20, is aiming to get in shape with cardio, weight training and stretching, and is making a fitness DVD with her trainer. "We're just trying to get healthy."

FAITH HILL

Turned 40: Sept. 21
The country superstar celebrated her big birthday with a bigger surprise from husband Tim McGraw: a party in Greece on the Onassis yacht with 30 friends and family members, including her brothers, who were meeting for the first time (Hill was adopted as an infant). It was "a dream," says the mom of three girls, who's looking to age gracefully and naturally. "I feel great about turning 40. I'm having the time of my life."

JOELY FISHER

Turned 40: Oct. 29
Kicking off the year, Fisher celebrated another milestone, her 10-year wedding anniversary to Christopher Duddy, with a New Year's Eve vows renewal on the beach in Mexico's Nuevo Vallarta – where the couple first honeymooned. Of the weekend-long party that drew family and friends, including Mariska Hargitay and Ricki Lake, mom of two Fisher told InStyle Weddings, "It was a magical moment."

MIRA SORVINO

Turned 40: Sept. 28
The Reservation Road actress has an Oscar, two babies and a husband nearly 15 years her junior, actor Christopher Backus. So what more could she want? "I'd love it," she joked to PEOPLE, "if I was independently wealthy and could stop acting and just focus on being a mom and activism." Already she's been working with the Global Fund for Children and has been vocal about human trafficking. "Help is not always reaching our most precious, vulnerable human beings," Sorvino told CNN. "You just want to scream and cry and do everything that you can."
