Jennifer Aniston "rediscovered" her hippy roots while shooting Wanderlust.

The actress starred alongside fiance Justin Theroux and Paul Rudd in the comedy, which was out earlier this year. The film follows a Manhattan couple who experiment with living in a rural commune where free love rules.

Jennifer says the plot resonated with her.

"I was definitely a hippy in my early twenties. At least in regards to the clothes. I loved that style. And I do like the attitude of being a little bit more carefree," she told the UK edition of OK! magazine.

"I actually rediscovered that while shooting Wanderlust. We were in a small town in the South and it was so great for me. I felt I was getting my anonymity back.

"My body just decompressed all of a sudden. It was very relaxing for me."

Jennifer says the downtime during filming was a welcome release for her.

"It changed me. I realised how stressed-out and how paranoid I am all the time. I feel so guarded and that makes it difficult to relax," she added.
