Watch your back, Jennifer Aniston
star, 44, made quite the fashion statement at Monday's premiere of Call Me Crazy
, a Lifetime film about mental illness.
Wearing a simple black romper with her hair tied back in a ponytail, the actress revealed a pattern of circular marks on her back – probably the result of cupping, a Chinese form of alternative medicine designed to promote circulation.
Cupping generally uses small glass bulbs that are heated and then placed on the skin, creating suction, often leaving red marks for a several days after treatment. Other famous fans of the treatment
include Gwyneth Paltrow
– remember when her's were the talk of the carpet?
But even concealer couldn't hide the marks left from cupping across Aniston's back.
Call Me Crazy
is composed of five short films about mental illness and boasts an all-star cast, including Jennifer Hudson
, Melissa Leo, Octavia Spencer, Sarah Hyland and Melanie Griffith.
