Jennifer Aniston has developed a “f**k it attitude”.

The 42-year-old star – who is currently dating ‘Your Highness’ actor Justin Theroux – admits she has become more comfortable with herself as she has grown older because she was a lot more “controlled” when she was younger.

She said: “Getting older, you get more comfortable in your body and in your skin and who you are and you have more of a f**k it attidue.

“You’re so careful and controlled in your 20s and you’re just more aware of your every move. Now, I think there’s more freedom and comfort and none of it really matters, as long as you are enjoying yourself and having a really good time. Not hurting other people – of course, that goes without saying.”

The former ‘Friends’ actress – who was formerly married to Brad Pitt – is now starring in comedy movie ‘Horrible Bosses’ as nymphomaniac blackmailer Dr. Julia Harris, and she admits she loved getting to explore her “kinkiest” side on the film.

She told The Sun newspaper: “It was great fun and very liberating to throw myself into this character. You feel totally uninhibited and get to explore your weirdest and kinkiest psychological quirks and just exaggerate all the kinds of flirtatious ideas and fantasies you’ve ever had.

“You get to enjoy being fearless when you play a character that is so brazen and domineering.”
