She arrived on the set of her movie Squirrel To The Nuts, with her highlighted blonde hair in a straight style and not a scrap of makeup on her complexion.
But after a couple of hours in her trailer, Jennifer Aniston was transformed by the afternoon. The actress had donned her dowdy brunette wig and a racy little black dress to film scenes for the comedy in New York City.
The body con frock fitted the star like a glove and showed off what appeared to be a slightly curvier frame.
Jennifer’s faux tresses are also more reminiscent of her early days playing Rachel in her hit series, Friends.
The engaged actress strutted from her trailer to the set in a pair of black strappy heels.
She also held a piece of paper, which appeared to be a script, in front of her. This time she had her face in full make-up after the sitting in her trailer for some time.
Earlier in the day, Jennifer was seen not quite so ready for her close-up as she headed to set. The former Friends star looked somewhat puffy in the face as the barefaced star prepared to sit down in the make-up artist’s chair.
Beating the current humidity in New York, Jen otherwise looked tanned and toned in a pair of denim drawstring shorts and a white tank top.
She accessorised the look with her favourite pair of espadrille sandals and silver drop earrings.
