London, May 11 (ANI): It turns out that Nicole Kidman is the one behind ‘Friends’ star Jennifer Aniston’s weight loss.

Aniston has apparently picked up Kidman’s strict healthy eating habits.

The pair, who hit it off on the Hawaiian set of their latest movie, ‘Just Go with It’, has forged a close bond since filming began.

Aniston, who was already a size 6 at the start of filming, has reportedly shed a further 4kg.

“The weight is falling off her. We’re worried she’s taken it too far.”

“Jen has always enjoyed her wine, cocktails and Mexican food but Nicole is much more strict about her diet and her habits have rubbed off,” The Herald Sun quoted a source as telling Grazia magazine.

The pair has been seen dining together on the set and eating undressed salads at Hawaii’s Spago restaurant with George Clooney, who is also filming on the island. (ANI)
