Nicole Kidman is reportedly looking to star in a movie about a "hot cougar".

The 45-year-old star has become increasingly comfortable with her body over the last few years. She appeared in risque movie The Paperboy alongside Zac Efron and it has apparently got her thinking about her future career choices.

"She feels like she's finally on top," a source told National Enquirer. "She is searching for a hot cougar script."

The star appears scantily clad on the cover of the fall Travel issue of V magazine. Although she wasn't sure about stripping off to begin with, those close to her convinced her it would look tasteful and sexy.

Nicole is now delighted she went through with the shoot.

"She found it incredibly liberating," the pal added. "She was thrilled with how the pictures turned out. But Nicole is more self-assured now than ever before. Her marriage to Keith Urban has given her a huge amount of strength."
