LOS ANGELES (Reuters) - Kate Hudson rose to movie stardom playing sweet All-American girls, but in her newest part in "My Best Friend's Girl," she relished doing two things she rarely does on film -- curse a lot and portray a sexually aggressive woman.

Since winning wide acclaim and an Oscar nomination as rock 'n' roll groupie Penny Lane in 2000's "Almost Famous," Hudson has worked in numerous romantic comedies including "How to Lose a Guy in 10 Days," "You, Me and Dupree" and "Fool's Gold."

But unlike the others that were aimed at audiences of most all ages, "My Best Friend's Girl," which debuts in theaters on Friday, features strong language and sexual content, which restricts the U.S. audience mostly to adults.

"I finally got to swear and say and do certain things that most people say to each other in normal, everyday life," Hudson said.

"I got a little taste of what those 'Sex and the City' girls were up to for so long, which was fun," she added, noting May's adult-oriented, blockbuster comedy based on the lives and love affairs of four single women living in New York City.

In "Best Friend's Girl," Hudson stars opposite Dane Cook and Jason Biggs, playing a lawyer who is scared away from monogamous affairs by her ex-lover (Biggs), and wants to make the best of being single with perennial bachelor Tank (Cook).

Tank, who has mastered the art of seducing and offending women, meets his equal in Alexis when he is hired by his best friend to steer her back toward him.

Cook, a stand-up comedian, praised Hudson's comic timing, saying she has the ability to work straight from the dialogue in a script or improvise with equal prowess.

"This is one of the funniest people that I've met," Cook told reporters at a recent news conference. "She has the Terminator exoskeleton version of the funny bone - she is so good, tremendously gifted, comedic person.

But Hudson, 29, daughter of actress Goldie Hawn, hasn't always been smiling in recent years as her personal life has seen highs-and-lows stemming from a widely-publicized divorce with from Black Crowes frontman Chris Robinson and troubled romance with actor Owen Wilson.

Hudson said she deals with negative news and the crush of media tabloids and paparazzi by retreating from the spotlight.

"I just go back to my life at home, my family, my son and my friends, and my experiences on set that I have with the people that I get to work with," Hudson said. "It makes everything okay and everything feel balanced."
